A D.C. generator works on the principle of____________?
Correct answer: C. Faraday's law of electromagnetic induction
- A. Lenz's law
- B. Ohm's law
- C. Faraday's law of electromagnetic induction
- D. none of the above
Explanation
A generator produces emf when conductors cut magnetic flux, as described by Faraday's law of electromagnetic induction. Lenz's law only gives the direction opposing the change, not the basic generation principle.
