Which of the following describes the formula representing Ohm's Law for electromotive force?

Ohm's Law is a fundamental principle in electrical engineering that describes the relationship between voltage, current, and resistance in a circuit. The correct formula for electromotive force (often represented as E) is expressed as E = I x R. In this formula, E denotes electromotive force (voltage) in volts, I represents current in amperes, and R signifies resistance in ohms.

This formula indicates that the electromotive force in a circuit is equal to the product of the current flowing through the circuit and the resistance that the current encounters. Understanding this formula is crucial for analyzing electrical circuits, as it allows one to calculate the voltage drop across a component or the required voltage to achieve a certain current flow, given a specific resistance.

The other formulas presented relate to different aspects of electrical circuits. For instance, P = V x I pertains to electrical power calculations, not directly to Ohm’s Law. I = V ÷ R rearranges Ohm’s Law but does not express it as electromotive force directly. Similarly, R = V ÷ I is another rearrangement of Ohm’s Law focusing on resistance. While all these equations are valid within the context of electrical principles, they do not specifically address the formula for electrom
