Assertion (A): No current can flow so long as an electric circuit is open. Reason (R ): Resistance of an open circuit is infinite.

Answer»

Both (A) and (R ) are true and (R ) is correct EXPLANATION of the assertion
Both (A ) and ( R) are true but (R ) is not the correct explanation of the assertion.
(A ) is true but (R ) is false
(A) is false but (R ) is true

Solution :RESISTANCE of an OPEN circuit is infinite (or exceedingly large) due to the presence of an air gap between the terminals of a key (SWITCH) and so no CURRENT can flow.
