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 a purely inductive or capacitive circuit, the current is referred to as wattless current. |
Reason (R): No power is dissipated in a purely inductive or capacitive circuit even though a current is flowing in the circuit. |
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: A
Solution :
(a) In a purely inductive or capacitive circuit, power factor, \[\cos \phi =0\] and no power is dissipated even though a current is flowing in the circuit. In such cases, current is referred to as wattless current.You need to login to perform this action.
