Question

Electric generator is a device which converts _______ energy into_______ energy.

1. Mechanical, electrical
2. Electrical, electronics
3. Electrical, chemical
4. Electrical, Mechanical

Answer 1

Correct Answer - Option 1 : Mechanical, electrical

The correct answer is Mechanical, electrical.

 

• In electricity generation, a generator is a device that converts mechanical energy into electrical power for use in an external circuit.
• Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines, and even hand cranks.

 

• Electric generators work on the principle of electromagnetic induction.
• A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet.
• The conductor coil along with its core is known as an armature.
• The armature is connected to a shaft of a mechanical energy source such as a motor and rotated.
• The mechanical energy required can be provided by engines operating on fuels such as diesel, petrol, natural gas, etc. or via renewable energy.
