Power in an electrical circuit is defined as:

Power in an electrical circuit is fundamentally defined as the rate at which energy is transferred or converted. Specifically, it is the amount of energy transferred in one second. This definition aligns with the formula for electrical power, which is often expressed as ( P = \frac{E}{t} ), where ( P ) is power, ( E ) is energy, and ( t ) is time.

This means that if you know how much energy is used in a circuit over a certain period, you can determine the power. In the context of electrical systems, power can also be calculated using laws like Ohm’s Law, but the underlying principle remains that power indicates how quickly energy is being used or delivered in the circuit.

The other options do not accurately define power; for instance, while the energy absorbed by a resistor is related to power, it does not encompass the idea of power as a rate of energy transfer. Current times resistance gives the voltage according to Ohm's Law, but it does not describe power directly. Lastly, total voltage supplied is a critical parameter in circuits but does not represent the rate of energy transfer, which is what defines power. Thus, the definition that associates power with energy transferred in one second captures
