Assertion : No power loss associated with pure capacitor in ac circuit. Reason : No current is flowing in this circuit.

Step-by-step solution

Assertion is true. When a capacitor is connected to an a.c. circuit, ( _ r m s =i_ r m s ( 1 C ) ) where ( 1 C ) is the impedance due to capacitative resistance. The power consumed in this circuit is zero because the phase difference ( ) between ( emf ) and current in a pure capacitance a.c. circuit is ( 2 ). Power factor ( =0 ). It is only for d.c. that a current does not flow. Reason is false.
