Concept explainers
What is wrong with this scheme? To generate electricity without fuel, arrange a motor to run a generator that will produce electricity that is stepped up with transformers so that the generator can run the motor and simultaneously furnish electricity for other uses.
To explain: issue with the scheme of generating the electricity without fuel, arranging a motor to run a generator that produces electricity
Explanation of Solution
Introduction: Energy can be transferred from one form to another form but
Explanation: Changing the voltage cannot change the amount of energy produced by the generator. The concept of the question is violating the law of conservation of energy.
According to II law of thermodynamics, any engine does not give
Conclusion: The idea of power generation in the question violating the law of conservation of energy.
