Question

Statement 1: Dynamo is used to generate electricity in thermal and hydro power plants.
Statement 2: Dynamo converts mechanical energy from turbine to electrical energy.
  1. Statement 1 is correct and statement 2 is incorrect.
  2. Statement 1 and statement 2 are correct, but statement 2 is not the reason for statement 1.
  3. Both statements are incorrect.
  4. Statement 1 and statement 2 are correct , and statement 2 is the reason for statement 1.


Solution

The correct option is D Statement 1 and statement 2 are correct , and statement 2 is the reason for statement 1.
Dynamo/generator is a device that converts rotational motion from the turbine shaft (mechanical energy) into electrical energy. This process is an application of electromagnetic induction. Thus, electricity is produced in thermal and hydro power plants using a turbine.
