Power is directly related to which two factors?

The correct response highlights the relationship between power, voltage, and current, which is defined by the formula ( P = VI ), where ( P ) represents power, ( V ) signifies voltage, and ( I ) denotes current. This fundamental principle in electrical engineering states that the power consumed or produced in a circuit is directly proportional to both the voltage across the circuit and the current flowing through it.

Understanding this relationship is crucial because it allows electricians and engineers to calculate the power requirements for electrical devices and systems accurately. Knowing that increasing either voltage or current will result in a corresponding increase in power is essential for ensuring that systems are designed and built to handle the expected electrical load.

In the context of electricity, options that connect resistance with voltage or power don't directly relate to how power itself is calculated. While resistance does play a role in electrical circuits, particularly in Ohm's Law (( V = IR )), it does not directly correlate to power in the same way voltage and current do.
