The device used to produce electric current is called :

Correct option is D

The correct answer is (d) Generator

A generator is a device used to convert mechanical energy into electrical energy, producing electric current. It works on the principle of electromagnetic induction.

Other Options:

• Galvanometer: A device used to measure small electric currents.
• Motor: A device that converts electrical energy into mechanical energy.
• Ammeter: An instrument used to measure the current flowing through a circuit.

Additional Information:
Electric current is the flow of electric charge through a conductor, such as a wire. It is typically caused by the movement of electrons in a circuit. Electric current is measured in amperes (A) and is produced when there is a potential difference (voltage) across a conductor, causing charges to move.

Key Points:

• Unit of Measurement: The unit of electric current is Ampere (A).
• Direction: The conventional direction of current is from positive to negative, though electrons flow from negative to positive.
