After You Build...Draw! • Complete all the challenges, drawing each one as a PROPER circuit diagram http://resources.schoolscience.co.uk/BritishEnergy/11-14/circh3pg1.html
Read and Make Notes • Complete all activities from pages 3 to 8 • Try the Test Bite on Page 6 • Be sure you know Potential Difference and Voltage
Write This Down Bolded Info! • Power means strength, or force or energy. To a scientist, power is the rate at which work is done or energy is used. Electric power is a measure of the rate at which electricity does work or provides energy. • For example, the power used to run a dishwasher is 2300 watts. • Watts (W) are the units in which electric power is measured. • Now remember, electric power measures the rate at which electricity does work or provides energy. • Electric power can be calculated by using the following equation: Power = Voltage x Current or P = V x 1 Another way to put it is Watts = Volts x Amperes • Think about a light bulb... The electricity in your home is 120 volts. The light bulb itself operates at o.5 ampere. According to the equation for power, multiplying these two numbers gives the bulb's wattage, which in this case is 60 watts.The wattage tells you the power of the bulb, or the rate at which energy is being delivered. THE HIGHER THE WATTAGE...THE BRIGHTER THE BULB...AND THE MORE EXPENSIVE TO RUN.
Complete This Activity The table below shows the power used by some common appliances. Which appliance would use the greatest amount of electric energy if operated for one hour? Which appliance listed uses the least number of watts?
