Electro Magnetic Induction And Alternating Currents Question 302
Assertion : Faraday’s laws are consequences of conservation of energy. Reason : In a purely resistive ac circuit, the current is in phase with the e.m.f. [AIIMS 2002]
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason are both false.
E) If assertion is false but reason is true.
Show Answer
Answer:
Correct Answer: C
Solution:
According to Faraday’s laws, the conversion of mechanical energy into electrical energy occurs. This is in accordance with the law of conservation of energy. It is also clearly known that in pure resistance, the emf is in phase with the current.
