Question

Calculate the potential difference across the ends of a wire of resistance 1ohm when a current of 3 A passes through it.

Answer 1

Answer:

#Given:

Current flowing through the circuit = 3 ampere

Resistance in the circuit = 1 ohm

#To find:

Potential difference across the resistance

#Concept:

Potential difference is the driving force for movement of electrons within a conductor such that current is generated through the circuit.

According to OHM'S LAW , If the physical parameters like temperature remain constant , the potential difference is directly proportional to the Current flowing through the circuit.

#Calculation:

=> V= I×R

=> V= 3×1

=> V= 3 Volt

So final answer is :

Potential difference across the resistance is 3 V
