Question

Calculate the rate at which energy is supplied by a 160 Volts battery to a circuit if the current in the circuit is 6 Amperes.

Answer 1

By definition, the rate of energy supply is the power dissipated in the circuit. The power is: $P = I\cdot V,$ where $I$ is the current in the curcuit and $V$ is the voltage across it. Thus:

$P = 160\cdot 6 = 960$ W.

Answer: 960 W.
