In the relationship P = EI, how would you express I if you have E and P?

The equation P = EI relates power (P), voltage (E), and current (I). To find an expression for current (I) given power and voltage, you need to isolate I in the equation.

Starting from the original equation P = EI, you can manipulate it by dividing both sides by E. This gives you I = P / E. This means that current is equal to power divided by voltage, which is the correct way to rearrange the formula.

This relationship is fundamental in electrical engineering, as it helps in calculating current when the power and voltage are known, making it crucial for analyzing electrical circuits. Understanding how to manipulate this formula is essential for anyone working in power engineering, as it allows for the determination of one variable when the others are known.
