Define 1 volt, Potential difference, Ohm's law in easy language

1 Volt

Potential Difference

  • The potential difference or voltage is given by current multiplied by the resistance.
  • When one Coulomb of charge flows between two points of a circuit, a voltage of one Volt equals one Joule of energy.

Ohm's law

  • Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it if all physical conditions and temperatures remain constant.
  • Ohm's law is a fundamental and important law of electric circuits.
