2) A lamp is plugged into a standard 120-volt outlet. If the lamp draws a current of 0.5-amps, how much energy is consumed in 1 minute?

A.) 3600 joules

Explanation:

Energy or work is power x time. Power is voltage x current. So, work is the product of voltage, current, and time. But time must be measured in seconds. So. the energy is (120) (0.5) (60) = 3600 joules

Power = (voltage) x (current)

Power = (120 V) x (0.5 Amp)

Power = 60 watts

Energy = (power) x (time)

Energy = (60 watts) x (60 seconds)

Energy = 3,600 watt-seconds

Energy = 3,600 Joules
