voltmeter
ammeter
motor
generator
This question was previously asked in
UPSC CAPF – 2022
The correct answer is D, generator.
A generator is a device that converts mechanical energy into electrical energy. This conversion is based on the principle of electromagnetic induction, where a relative motion between a conductor and a magnetic field induces an electric current in the conductor. Mechanical work is done to cause this relative motion.
A motor is a device that converts electrical energy into mechanical energy.
A voltmeter is an instrument used to measure electric potential difference (voltage).
An ammeter is an instrument used to measure electric current.
Generators are essential components in power plants, converting mechanical energy from sources like turbines (driven by steam, water, or wind) into electrical energy for distribution.
