Ohm's Law is a fundamental principle in electrical engineering and states the relationship between voltage, current, and resistance. The law can be mathematically expressed as E = I x R, where E represents the voltage (electromotive force) in volts, I represents the current in amperes, and R represents the resistance in ohms.

In this equation, multiplying current (I) by resistance (R) gives the voltage (E) across a component in a circuit. This relationship shows that for a given resistance, if the current increases, the voltage will also increase proportionally, illustrating how the three quantities interact in electrical circuits.
