One coulomb charge contains nearly 6 × 1018 electrons. In a circuit having metallic wires, the electrons establish the flow of charges. The direction of the electric current is considered opposite to the direction of the flow of electrons. Electrons are the negative charges.

Answer: There are total 6 × 1018 electrons in one coulomb charge.

An electron possesses a negative charge of 1.6 × 10-19C. The movement of electrons in a metallic wire is possible only when there is a difference of electric pressure called the potential energy. The motion of electrons in an electric circuit develops electric current.

More about Electrons in an Electric Circuit

More information related to the motion of electrons in an electric circuit has been elaborated below:

  • Electrons are not consumed in an electric circuit.

  • A battery or cell is used for setting up the motion of the electrons in an electric circuit.

  • Thus, the movement of electrons constitutes an electric current in the circuit.

  • Ampere is the SI unit of electric current.

  • The property that resists the flow of electrons is known as resistance. Its SI unit is ohm.

  • Resistance regulates the magnitude of the current.
