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 capacitive reactance limits the amplitude of the current in a purely capacitive circuit. |
Reason (R): Capacitive reactance is proportional to the frequency and the capacitance. |
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 capacitive reactance limits the amplitude of the current in a purely capacitive circuit in the same way as the resistance limits the current in a purely resistive circuit. i.e., \[{{l}_{0}}=\frac{{{\varepsilon }_{0}}}{{{X}_{C}}}\] But it is inversely proportional to the frequency and the capacitance.You need to login to perform this action.
