Which Type/Types of Power Generation Involve Maximum Number of Steps of Energy Conversion? in Which Power Generation is the Number Minimum?
Answers
Answer:
The power generation using solar photovoltaic cell involves least number of steps of energy conversion.
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 cell involves least number of steps of energy conversion. It involves only two steps of energy conversion.
Energy in sunlight→electric energy
