What is the formula for Ohm's Law?

Ohm's Law is a fundamental principle in electrical engineering that relates voltage, current, and resistance in an electrical circuit. The correct formula, represented as V = I * R, indicates that the voltage (V) across a conductor is equal to the current (I) flowing through it multiplied by the resistance (R) of that conductor.

This relationship defines how electrical components behave in a circuit. Specifically, it tells us that if we know the current flowing and the resistance in the circuit, we can calculate the voltage across that component. This principle is crucial for designing and analyzing electrical circuits, as it allows engineers to predict how changes in current or resistance will impact the voltage.

In a practical context, understanding Ohm's Law enables engineers to determine the appropriate sizes of wires, the necessary ratings for components like resistors, and the overall functioning of complex circuit designs. Thus, the formula V = I * R serves as a foundation for understanding and applying electrical engineering concepts.
