Ohm's Law

Ohm's law

Ohm's Law describes the linear relationship between voltage (V), current (I), and resistance (R) in a circuit, with the most common formula being V = I × R. Voltage is the electric potential difference, current is the rate of charge flow, and resistance is the opposition to that flow, measured in ohms (Ω). This law is a fundamental principle in electronics used to calculate any of the three variables if the other two are known.
