In Ohm's Law, what does the letter I represent?

In Ohm's Law, the letter I represents Current. This fundamental equation in electrical engineering relates voltage (V), current (I), and resistance (R) through the formula V = I × R. In this context, current is the flow of electric charge, measured in amperes (A).

Understanding that current is denoted by I is crucial because it helps define how much electricity is flowing through a circuit at any given moment. The knowledge of this relationship allows engineers and technicians to design and troubleshoot electrical systems effectively.

Resistance, voltage, and power have distinct definitions in this context. Resistance refers to the opposition to the flow of electric current, voltage is the potential difference that drives the current, and power measures the rate at which energy is used or generated in an electrical system. However, in the specific framework of Ohm's Law, the letter I unequivocally signifies current.
