Question

what is ohm's law?....................................
​

Answer 1

Answer :-

Ohm's Law states that the current flowing in a circuit is directly proportional to the applied potential difference and inversely proportional to the resistance in the circuit. In other words by doubling the voltage across a circuit the current will also double.

V = IR

Here ,

• V is Voltage.
• I is Current.
• R is Resistance.
