Question

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

Answer:

(ii) nuclear energy based power generation: it also involves 5 steps of energy conversion. the power generation using solar photovoltaic cell involves least number of steps of energy conversion. it involves only two steps of energy conversion.

Answer 2

Answer:

The types of power generation involving maximum number of steps of energy conversion are:

(i) Thermal energy based power generation: It involves 5 steps of energy conversion.

Chemical energy in coal→thermal energy→kinetic energy in steam→kinetic energy in turbine→electrical energy

(ii) Nuclear energy based power generation: It also involves 5 steps of energy conversion.

Nuclear energy→thermal energy→kinetic energy in steam→kinetic energy in turbine→electrical energy

The power generation using solar photovoltaic cells involves the least number of steps of energy conversion. It involves only two steps of energy conversion.

Energy in sunlight→electric energy
