All of the following are correct formulas for ohm's law except?

Ohm's Law is a fundamental principle in electrical engineering that relates voltage (V), current (I), and resistance (R). The standard formulas that arise from Ohm's Law are:

1. Voltage calculation: V = I x R, which states that voltage is equal to current multiplied by resistance.

2. Resistance calculation: R = V / I, which tells us that resistance is the voltage divided by current.

3. Power calculation: P = V x I, defines electric power as the product of voltage and current.

The choice that does not correctly represent a formula consistent with these principles is E = P x I. This formula incorrectly suggests that power equals voltage multiplied by current in a way that is not aligned with the standard conventions of Ohm's Law.

Power is actually calculated in relation to voltage and current as P = V x I, and not by multiplying power with current again. The context and usage of each formula are critical in understanding electrical circuits, but only the correct formulations stemming from Ohm's Law will help in accurately analyzing electrical systems.
