  6. Charge is a fundamental property of matter that indicates how the matter will behave in an electric or a magnetic field. • Unit of Charge is the Coulomb, 1 electron has a charge of -1.6 x 10-19 C. => 1 C requires 1018 e- s • There are two types of Charge: Positive(+) and Negative(-) • Ben Franklin first proposed the laws of Charge • Like Charges Repel • Opposite Charges Attract • Most objects are charged by an excess (-) or a deficiency (+) of electrons.

  12. Current is the amount of charge which moves past a given reference point in a given amount of time. • The unit of Current is the Ampere. 1 A = 1 C/s • Voltage is the amount of Electrical Potential Energy per unit Charge at a point. • The unit of Voltage is the Volt. 1 V = 1 J/C. • J (Joule) is a unit of energy. • 1 J is the amount of energy a 2 kg mass has when moving 1 m/s, or 4.186 J is the energy needed to heat 1 g of water 1˚C. (ie. 4.186 J is 1 Calorie)

  13. Current goes from Higher Voltage (more +) to Lower Voltage (more -). • + Charges are repelled by Higher (+) Voltages and attracted to Lower (-) Voltages. • - Charges are attracted to Higher (+) Voltages and repelled by Lower (-) Voltages. • Currents are defined by the direction a (+) charge would take in a circuit.

  14. Water Analogy of Electricity • Current is analogous to Water Flow (ie how much water flows in the pipe?). • Voltage is analogous to Water Pressure (ie how much energy does the water in the pipe have?). • Resistance is the opposition to current flow. It is analogous to impediments in the pipe, debris, friction, changes in pipe diameter, etc.

  29. An Electrical Circuit is a collection of Electrical Elements connected together. • Electrical Elements are Power Providers (Batteries), Power Using Devices (Lights, motors, etc), and Connective Elements (Wires). • A circuit will have electrical current flow through it only if the circuit is complete. The circuit begins on or at a High Voltage point and it must end on or at a Low Voltage point. Often these are two parts of a Power Providing Device.
