Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit.
what is ohm's law?
Ohm’s law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm’s law is V=IR.
Mathematically, Ohm’s law can be expressed as,
I ∝V
Introducing the constant of proportionality, the resistance R in the above equation, we get,
I=V/R or V= I×R
Where,
R is the resistance of the conductor in Ohm
I is the current through the conductor in Amperes (A),
V is the voltage or potential difference measured across the conductor in Volts (V).
