What is Ohm’s Law? Ohm’s Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. Ohm’s Law Formula. Ohm’s Law is fundamental in the study of electricity, and its formula is given by: V = IR. Where:
The Ohm’s Law Formula. The mathematical expression of Ohm’s Law is: V = I × R V = I \times R. Where: V V is the voltage (in volts, V) across a conductor or component.. I I is the current (in amperes, A) flowing through the component.. R R is the resistance (in ohms, Ω) of the conductor..
