Quizplus · Accepted Answer

For an appliance to receive and consume electric power, a current must flow through it across a voltage decrease. This is because electrical power is the product of current and voltage difference (P=IV), and for power to be consumed, energy must be transferred from the power source to the appliance, which occurs as the current flows through the appliance from a higher to a lower voltage.
