What is Ohm’s Law ?
Ohm’s Law is a fundamental concept in electronics that explains the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. According to Ohm’s Law, the current passing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them.
This relationship is expressed by the formula: V = I × R, where:
–V is the voltage measured in volts (V)
–I is the current measured in amperes (A)
–R is the resistance measured in ohms (Ω)
