What Exactly is Ohm’s Law?

Discovered by German physicist Georg Simon Ohm in 1827, this fundamental law establishes the relationship between three core electrical parameters: Voltage (V), Current (I), and Resistance (R). The 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.

The Mathematical Expression:
V = I × R
Where:

• V = Voltage in Volts (V)

• I = Current in Amperes (A)

• R = Resistance in Ohms (Ω)
