Electricity and Ohm's Law These are the four basic units of electricity: • Voltage (V) • Current (I) • Power (P) • Resistance (R) Menerapkan teknik elektronika analog dan digital dasar Module1 Electronica analog and Digital system
Definition Voltage, current, power, and resistance are electronic terms that a computertechnician must know: • Voltage is a measure of the force required to push electrons through a circuit. • Voltage is measured in volts (V). A computer power supply usually produces several different voltages. • Current is a measure of the amount of electrons going through a circuit. • Current is measured in amperes, or amps (A). Computer power supplies deliver different amperages for each output voltage. Menerapkan teknik elektronika analog dan digital dasar Module1 Electronica analog and Digital system
Definition • Power is a measure of the pressure required to push electrons through a circuit, called voltage, multiplied by the number of electrons going through that circuit, called current. The measurement is called watts (W). Computer power supplies are rated in watts. • Resistance is the opposition to the flow of current in a circuit. Resistance is measured in ohms. Lower resistance allows more current, and therefore more power, to flow through a circuit. A good fuse will have low resistance or a measurement of almost 0 ohms.

Ohm's Law • There is a basic equation that expresses how three of the terms relate to each other. It states that voltage is equal to the current multiplied by the resistance. This is known as Ohm's Law. V = IR • In an electrical system, power (P) is equal to the voltage multiplied by the current. P = VI • In an electrical circuit, increasing the current or the voltage will result in higher power.

As an example of how this works, imagine a simple circuit that has a 9 V light bulb hooked up to a 9-V battery. The power output of the light bulb is 100-W. Using the equation above, we can calculate how much current in amps would be required to get 100-W out of this 9-V bulb. Menerapkan teknik elektronika analog dan digital dasar Module1 Electronica analog and Digital system
To solve this equation, we know the following information: P = 100 W V = 9 V I = 100 W/9 V = 11.11 A What happens if a 12-V battery and a 12-V light bulb are used to get 100 W of power? 100 W / 12 V = 8.33 amps This system produces the same power, but with less current.

Application to computer • Computers normally use power supplies ranging from 200-W to 500-W. However, some computers may need 500-W to 800-W power supplies. When building a computer, select a power supply with sufficient wattage to power all of the components. Obtain the wattage information for the components from the manufacturer's documentation. When deciding on a power supply, make sure to choose a power supply that has more than enough power for the current components.

Math for a Digital Age A. Measurement-related terminology When working in the computer industry, it is important to understand the terms that are used. Whether reading the specifications about a computer system, or talking with another computer technician, there is a rather large dictionary of terms that should be known. The technician needs to know the following terminology: • bit – The smallest unit of data in a computer. A bit can take the value of either one or zero. A bit is the binary format in which data is processed by computers. • byte – A unit of measure that is used to describe the size of a data file, the amount of space on a disk or other storage medium, or the amount of data being sent over a network. One byte consists of eight bits of data. • nibble – Half a byte or four bits. Menerapkan teknik elektronika analog dan digital dasar Depan Module1 Electronica analog and Digital system
kilobyte (KB) – 1024, or approximately 1000, bytes. • kilobytes per second (kBps) – A measurement of the amount of data that is transferred over a connection such as a network connection. kBps is a data transfer rate of approximately 1,000 bytes per second. • kilobit (Kb) – 1024, or approximately 1000, bits. • kilobits per second (kbps) – A measurement of the amount of data transferred over a connection such as a network connection. kbps is a data transfer rate of approximately 1,000 bits per second. • megabyte (MB) – 1,048,576 bytes, or approximately 1,000,000 bytes. Menerapkan teknik elektronika analog dan digital dasar Module1 Electronica analog and Digital system
megabytes per second (MBps) – A common measurement of the amount of data transferred over a connection such as a network connection. MBps is a data transfer rate of approximately 1,000,000 bytes or 106 kilobytes per second. • megabits per second (Mbps) – A common measurement of the amount of data transferred over a connection such as a network connection. Mbps is a data transfer rate of approximately 1,000,000 bits or 106 kilobits per second. Menerapkan teknik elektronika analog dan digital dasar Module1 Electronica analog and Digital system
Note: • A common error is confusing KB with Kb and MB with Mb. A capital B indicates bytes while a lower case b indicates bits. Similarly, multipliers greater than one are capitalized and multipliers less than one are lower case. • For example, M=1,000,000 and m=0.001. Remember to do the proper calculations when comparing transmission speeds that are measured in KB with those measured in Kb. • For example, modem software usually shows the connection speed in kilobits per second, such as 45 kbps. However, prominent browsers display file-download speeds in kilobytes per second. Therefore, the download speed with a 45-kbps connection would be a maximum of 5.76-kBps. Menerapkan teknik elektronika analog dan digital dasar Module1 Electronica analog and Digital system
In actual practice, the download speed of a dialup connection cannot reach 45 kbps because of other factors that consume bandwidth at the same time as the download. The technician needs to know the following terminology: • hertz (Hz) – A unit of frequency measurement. It is the rate of change in the state, or cycle, in a sound wave, alternating current, or other cyclical waveform. Hertz is synonymous with cycles per second, and it is used to describe the speed of a computer microprocessor. Menerapkan teknik elektronika analog dan digital dasar Module1 Electronica analog and Digital system
megahertz (MHz) – One million cycles per second. This is a common measurement of the speed of a processing chip. • gigahertz (GHz) – One billion cycles per second. This is a common measurement of the speed of a processing chip. • Note: PC processors are becoming faster all the time. The microprocessors used on PCs in the 1980s typically ran under 10 MHz, and the original IBM PC was 4.77 MHz. In the start of the year 2000, PC processors approached the speed of 1 GHz, and approached 3.0 GHz as of the year 2002.

Digital signal The variables that characterize digital systems only occupy a fixed number of discrete values. In binary arithmetic, as used in computers, only two values are allowed. These values are 0 and 1. Computers and cable modems are examples of digital devices. Figure 2 shows a diagram of a digital signal.

B. Boolean logic gates Computers are built from various types of electronic circuits. These circuits depend on what are called AND, OR, NOT, and NOR logic gates. These gates are characterized by how they respond to input signals. Figures , and show logic gates with two inputs. The ”x” and ”y” represent inputs, and the ”f” represents output. Think of 0 (zero) as representing “off” and 1 as representing “on”. Menerapkan teknik elektronika analog dan digital dasar HOME Module1 Electronica analog and Digital system
There are only three primary logic functions. They are AND, OR, and NOT: • AND gate – If either input is off, the output is off. • OR gate – If either input is on, the output is on. • NOT gate – If the input is on, the output is off. The same is true of the opposite. • The NOR gate is a combination of the OR and NOT gates and should not be presented as a primary gate. A NOR gate acts if either input is on, the output is off. • The “truth tables” in Figure represent these statements in a compact form. Other logic gate combinations or extensions such as XOR, NAND.

Digital Age System Decimal and binary number systems • The decimal, or Base 10, number system is used every day for doing math such as counting change, measuring, telling time, and so on. The decimal number system uses ten digits including 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. • The binary, or Base 2, number system uses two digits to express all numerical quantities. The only digits used in the binary number system are 0 and 1. An example of a binary number is 1001110101000110100101.

Decimal Number Systems Menerapkan teknik elektronika analog dan digital dasar Module1 Electronica analog and Digital system
Binary Number System Menerapkan teknik elektronika analog dan digital dasar Module1 Electronica analog and Digital system
The binary, or Base 2, number system uses two digits to express all numerical quantities. The only digits used in the binary number system are 0 and 1. An example of a binary number is 1001110101000110100101. • It is important to remember the role of the digit 0. Every number system uses the digit 0. However, note that whenever the digit 0 appears on the left side of a string of digits, it can be removed without changing the string value. For example, in Base 10, 02947 is equal to 2947. In Base 2, 0001001101 is equal to 1001101. Sometimes people include 0s on the left side of a number to emphasize “places” that would otherwise not be represented. Menerapkan teknik elektronika analog dan digital dasar Module1 Electronica analog and Digital system
Another important concept when working with binary numbers is the powers of numbers. The numbers 20 and 23 are examples of numbers represented by powers. These examples are spoken as “two to the zero” and “two to the third”. The power is the number of times that a value must be multiplied by itself. For example, 20 = 1, 21 = 2, 22 = 2 x 2 = 4, 23= 2 x 2 x 2 = 8. Taking powers is commonly confused with simple multiplication For example, 24 is not equal to 2 x 4 = 8. However, 24 is equal to 2 x 2 x 2 x 2 = 16. Menerapkan teknik elektronika analog dan digital dasar Module1 Electronica analog and Digital system
In Base 10, powers of ten are used. For example, 23605 in Base 10 means 2 x 10,000 + 3 x 1000 + 6 x 100 + 0 x 10 + 5 x 1. • Note that 100 = 1, 101= 10, 102= 100, 103= 1000, and 104 = 10,000. • Caution: Although 0 x 10 = 0, do not leave it out of the above equation. If it is left out, the base 10 places all shift to the right and result in the number 2,365 = 2 x 1,000 + 3 x 100 + 6 x 10 + 5 x 1 instead of 23,605. A 0 within a number should never be ignored. However, the value of a number is not affected by adding zeros onto the beginning, or by ignoring zeros that are on the beginning of the number. For example, 23,605 can be expressed as 0023605.

Decimal to binary conversion • More than one method exists to convert binary numbers. One method is explored here. However, the student should feel free to use another method if it is easier.
