Question

Assertion : Faraday's laws are consequences of conservation of energy.
Reason : In a purely resistive A.C. circuit, the current lags behind the e.m.f. in phase.

• A. If both the assertion and reason are true and reason is a correct explanation of the assertion
• B. If both assertion and reason are true but assertion is not a correct explanation of the assertion
• C. If the assertion is true but the reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (C)

Faraday’s laws involve conservation of mechanical energy into electrical energy. This is in accordance with the law of conservation of energy. We also know that in pure resistance, the e.m.f. is in phase with the current.
