Which of the following methods of generating electricity is the only one that does NOT rely on Faraday's law of electromagnetic induction?
A. Wind turbines
B. Nuclear power plant
C. A conventional fossil fuel power plant, burning coal, oil, or natural gas
D. Solar photovoltaics (solar panels)
E. Hydro-electric power plant
Only solar photovoltaic method does not depend on the Faraday's law of induction. As in solar energy electrons absorbs energy from sunlight and gets excited and create a voltage difference in silicon devices which is then stored in batteries.
Wind turbines convert wind energy to mechanical work and the mechanical work is converted to electric energy by generator which works on Faraday's law of induction
Nuclear power plant uses nuclear energy to heat up water steams so that heat energy from water is converted to electric energy by the generator.
In fossil fuel power plant, fossil fuels are burned to heat water and then heat energy is converted into electric energy by generator.
In hydro electric power plant water falls on turbine and turbine works on Faraday's law of induction.
That's why solar energy is the right answer.
Hope it helps...
Please give me a thumbs up....
