Thermal Power Plants

Q. What is the name of device which is used to convert mechanical energy into electrical energy?

1. Dynamo
2. Heater
3. Turbine
4. Boiler

Q. Why are most of thermal power plants located near coal mines?

1. It is necessary to transport coal to power plant immediately else the coal will disintegrate.
2. Coal gets wet when it comes in contact with air and is rendered useless.
3. Places near to thermal power plants are cheaper.
4. It is more economical to transmit electricity than to transport coal.
