In the circuit shown here, the point 'C' is kept connected to pointA'' till the current flowing through the circuit becomes constant. Afterward, suddenly, point 'C' is disconnected from pointA'' and connected to point 'B' at timet=0. Ratio of the voltage across resistance and the inductor att=LRwill be equal to :

Question diagram: In the circuit shown here, the point ' C ' is kept
