What is the formula for calculating E when given P and I using the equation P = EI?

The formula for calculating E when given power (P) and current (I) using the equation P = EI is derived by rearranging the original formula. In the equation P = EI, power (P) is the product of voltage (E) and current (I). To isolate voltage (E), you would divide both sides of the equation by current (I), resulting in E = P / I.

This relationship indicates that the voltage is equal to the power divided by the current, establishing a direct calculation method for voltage when you know the other two variables. This is fundamental in electrical engineering, as understanding how these quantities relate is essential for analyzing and designing electrical systems.
