Solution
Step1: 1Volt
Volt is the electrical unit of voltage or potential difference (V).
We get a 1 Volt potential difference when a change of 1 joule of Potential energy is there in moving a charge of 1 Coulomb.
One joule of work is required to move a one-coulomb electric charge across a one-volt potential difference.
One volt corresponds to one joule per coulomb.
Step2: Potential difference
The potential difference (also known as voltage) is equal to the current multiplied by the resistance.
When one Coulomb of charge flows between two points in a circuit, a potential difference of one Volt equals one Joule of energy.
Step3: Ohm's law
Ohm's law is one of the most fundamental and important laws of electric circuits.
Ohm's law states that if all physical conditions and temperatures remain constant, the voltage across a conductor is directly proportional to the current flowing through it.
