Question

Statement 1: Dynamo is used to generate electricity in thermal power plant, a hydropower plant and wind energy plant.

Statement 2: Dynamo converts mechanical energy from turbine to electrical energy.

• A. Both statements are correct, and statement 2 is the correct explanation for statement 1.
• B. Both statements are correct, but statement 2 does not explain statement 1.
• C. Only statement 1 is correct.
• D. Only statement 2 is correct.

Answer 1

The correct option is A Both statements are correct, and statement 2 is the correct explanation for statement 1.

Dynamo is a device used in all power plants. A dynamo converts mechanical energy to electrical energy. When the coil of dynamo is rotated in a magnetic field, electrical energy is generated.

Since the power plants are built to deliver electrical energy, a dynamo (or a generator) is essential for all power plants.

Hence, both statements are correct. Statement 2 explains statement 1.
