According to the formula for power, which variable is not directly accounted for when determining power?

In the context of determining power in electrical circuits, the most commonly used formula is P = VI, where P represents power, V is voltage, and I is current. This formula establishes a direct relationship between power and both voltage and current, meaning both of these variables are directly accounted for in power calculations.

Resistance, on the other hand, is related to power through Ohm’s law (V = IR) and can be indirectly considered when analyzing power in certain contexts. While resistance influences how voltage and current behave in a circuit, it is not a separate variable directly included in the power formula of P = VI. Instead, resistance may influence the values of voltage or current, but it does not appear explicitly in the basic power calculations.

Therefore, when determining power using the fundamental power formula, resistance is the variable that is not directly included in the equation alongside voltage and current.
