Step 1: Understand Each Device.
Let's analyze each option to determine which device is used for producing electric current:
1. Generator:
A generator converts mechanical energy into electrical energy by rotating a coil in a magnetic field or moving a conductor through a magnetic field. This is the primary function of a generator.
2. Galvanometer:
A galvanometer is an instrument used to detect and measure small electric currents. It does not produce electric current but measures it.
3. Ammeter:
An ammeter is a device used to measure electric current. Like the galvanometer, it does not produce electric current but measures it.
4. Motor:
A motor converts electrical energy into mechanical energy. It consumes electric current rather than producing it.
Step 2: Analyze the Options.
Option (1): Generator — Correct, as generators are specifically designed to produce electric current.
Option (2): Galvanometer — Incorrect, as it measures current, not produces it.
Option (3): Ammeter — Incorrect, as it measures current, not produces it.
Option (4): Motor — Incorrect, as motors consume current, not produce it.
Step 3: Final Answer.
