Question

Which of the following statement is true regarding the hydropower plant?

• A. The potential energy possessed by the stored water is converted into electricity.
• B. Kinetic energy possessed by the stored water is converted into potential energy.
• C. Electricity is extracted from the chemical energy possessed by water.
• D. Water is converted into steam to produce electricity.

Answer 1

The correct option is A

The potential energy possessed by the stored water is converted into electricity.

Water stored in a dam at a certain height, has potential energy. This potential energy is converted to kinetic energy when allowed to flow. The kinetic energy of flowing water is used to turn the turbine, which is used to generate electric current. Hence, the overall conversion is from the potential energy of stored water to electrical energy.
