Electro Magnetic Induction And Alternating Currents Question 113
Question: Assertion : In series LCR circuit resonance can take place. Reason : Resonance takes place if inductance and capacitive reactances are equal and opposite. [AIIMS 1998]
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 both are false.
E) If assertion is false but reason is true.

Answer:
Correct Answer: A
Solution:
At resonant frequency,
$ X_{L}=X_{C} $ \ $ Z=R $ (minimum) there for current in the circuit is maximum.
