Lenz's law is a consequence of the law of conservation of__________?
Correct answer: C. energy
- A. induced current
- B. charge
- C. energy
- D. induced e.m.f.
Explanation
Lenz's law gives the induced emf a direction that opposes the change producing it, preventing energy from appearing without an input. Thus, it follows from conservation of energy, not conservation of charge.
