Alternating Current

JEE Main level, single correct, medium

145 of 190

Question 145 of 190

In the circuit shown here, the point ' $C$ ' is kept connected to point $A$ '' till the current flowing through the circuit becomes constant. Afterward, suddenly, point ' $C$ ' is disconnected from point $A$ '' and connected to point ' $B$ ' at time $t=0$ . Ratio of the voltage across resistance and the inductor at $t=\dfrac{L}{R}$ will be equal to :

Show answer and solution

Answer: (C) - 1

Applying Kirchhoff's law in closed loop,

-{V}_{R}-{V}_{L}=0

\Rightarrow \dfrac{{V}_{R}}{{V}_{L}}=-1
