Choose the correct statement.

  1. Power of magnets in hydro power plants increases with time.

  2. Magnets are involved in the generation of electricity in hydro power plants.

  3. In hydro power plants, magnetic energy is converted into electrical energy.

  4. In hydro power plants, electrical energy is converted into magnetic energy.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Magnets slowly lose their strength with time.

In hydro power plants, kinetic energy from water is converted to electrical energy. This is done with the help of magnets. A coil is rotated (from kinetic energy of water) between two magnets to generate electricity.

Production of electricity by wave energy requires:

  1. extremely strong pipes to carry sea water in huge waves.

  2. devices to trap wave energy for rotation of turbine.

  3. devices to boil sea water in waves.

  4. all of the above.
