Read the scenario and answer the accompanying questions.
Electrical current is the flow of electrons through a wire and is measured in amperes (amps) . The voltage (volts) is a measure of the electric force required to keep electrons flowing through a wire. Power is the rate at which electricity does work, or provides energy, and is measured in watts (W) . The current and voltage are related to electric power by the following equation: Power = volts × amps. Large amount of electric power is measured in kilowatts (kW) . An electric bill reflects the total amount of electrical energy (expressed in kilowatt-hours, kWh) , used by all electric appliances for the duration of the time (in hours) they were being used. Thus: kWh = (W × h) ÷ 1000.
