The law that the induced e.m.f. and current always oppose the cause producing them is due to____________?
Correct answer: B. Lenz
- A. Faraday
- B. Lenz
- C. Newton
- D. Coulomb
Explanation
Lenz’s law states that induced emf and current oppose the change or cause producing them. Faraday’s law gives the magnitude and direction sign convention, but the opposition principle is due to Lenz.
