Question

How do we use a dam to generate electricity?

A) The pressure of the water against the dam spins a turbine.
B) When waves lap against the wall of the dam, a wheel is spun.
C) Water flowing through an intake pipe causes a turbine to spin.
D) When the water flows over the top of the dam, the water spins a wheel as it falls down.

Answer 1

when water from a dam passes through, turbines spin and those turbines generate electricity. This would make C the better answer.

Answer 2

c) Water flowing through an intake pipe causes a turbine to spin.

Step-by-step explanation:

The production of hydro electrical power can be done when the water passes from the dam to the rivers which are below dam.

The energy is based on the amount or pressure of the water if the more water is passing through the intake pipe then there is more production of energy. An artificial lake is created behind the dam.

Turbines which are surrounded by magnets produce the electricity when the flowing water is hit on the turbines than turbines rotates and produce electricity and turbines are present in the dam.

Therefore, water which is flowing through an intake pipe causes spinning of turbine which produce electricity.
