| Directions: In the following questions, a statement of Assertion [A] is followed by a statement of Reason (R). |
| Mark the correct choice as: |
| Assertion [A]: In series LCR resonance circuit, the impedance is equal to the ohmic resistance. |
| Reason (R): At resonance, the inductive reactance exceeds the capacitive reactance. |
A) Both Assertion [A] and Reason (R) are true and Reason (R) is the correct explanation of Assertion [A]
B) Both Assertion [A] and Reason (R) are true but Reason (R) is not the correct explanation of Assertion [A]
C) Assertion [A] is true but Reason (R) is false
D) Assertion [A] is false and Reason (R) is also false
Correct Answer: C
Solution :
(c) In series resonance circuit, inductive reactance is equal to capacitive reactance. i.e., \[\omega L=\frac{1}{\omega C}\] \[\therefore Z=\sqrt{{{R}^{2}}+{{\left( \omega L-\frac{1}{\omega C} \right)}^{2}}}=R\]
