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.
-If a household appliance is operating on 110 volts and electricity is flowing with a current of 0.2 amperes in this appliance, how many watts are consumed?

Quizplus · Accepted Answer

The power consumed can be calculated using the formula: Power = volts × amps. Here, Power = 110 volts × 0.2 amps = 22 watts.
