Question

4. Which type/types of power genera-
tion involve maximum number of
steps of energy conversion? In which
power generation is the number
minimum?​

Answer 1

Thermal power plants are the power generation plant that needs the maximum steps in energy conversion.

In a thermal power plant, the heat is transferred into gaseous form and then into electricity which involves a number of steps. These power station also include conversion of energy from mechanical power into electrical power.

The motion between the magnetic field creates current. Lord Armstrong in England designed the first station in 1870.

Answer 2
