| 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]: The inductive reactance limits amplitude of the current in a purely inductive circuit. |
| Reason (R): The inductive reactance is independent of the frequency of the current. |
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) The inductive reactance limits the amplitude of current in a purely inductive circuit in the same way as the resistance limits the current in a purely resistive circuit. i.e., \[{{l}_{0}}=\frac{{{\varepsilon }_{0}}}{{{X}_{L}}}\] The inductive reactance is directly proportional to the inductance and the frequency of the circuit.
