Which formula is used to calculate the amount of Current, or load, in Amperes required by a piece of equipment?

The formula that is used to calculate the amount of Current, or load, in Amperes required by a piece of equipment is P/E = I. This formula effectively rearranges the basic power equation, P = I x E, where P represents power in watts, I is the current in amperes, and E is the voltage in volts. By adjusting the formula to isolate I (the current), you arrive at I = P/E, which can also be written as P/E = I, focusing on how much current is drawn based on the power and voltage involved.

Understanding this relationship is crucial in show production, as it helps in determining how much electrical load equipment will require, ensuring that circuits are not overloaded and that all devices are operating safely and efficiently within their electrical parameters.
