You are given many resistances, capacitors and inductors. These are connected to a variable DC voltage source (the first two circuits) or an AC voltage source of 50 Hz50 \mathrm{~Hz} frequency (the next three circuits) in different ways as shown in Column II. When a current II (steady state for DC or rms for ACA C ) flows through the circuit, the corresponding voltage V1V_1 and V2V_2 (indicated in circuits) are related as shown in Column I. Match the two You are given many resistances, capacitors and inductors. These are connected to a variable DC voltage source (the

  4. D(A) S,T, (B) Q,R,S,T, (C) P, (D) Q,R,S

Correct answer

B. (A) R,S,T, (B) Q,R,S,T, (C) P,Q, (D) Q,R,S,T

Step-by-step solution

In circuit (P), I can't be non zero in steady state. In circuit (Q) : V1=0andV2=2I=VV_1=0 and V_2=2 I=V (also)  In  circuit (R): V1=XLI=(2πfL)I=(2π×50×6×10−3)I=1.88IV2=2I\begin{aligned} & \text{\text{ In } circuit (R): } V_1=X_L I=(2 \pi f \mathrm{ L}) I \\ & \quad=\left(2 \pi \times 50 \times 6 \times 10^{-3}\right) I \\ & \quad=1.88 I \\ & V_2=2 I \end{aligned} In circuit (S): V1=XLI=1.88IV_1=X_L I=1.88 IV2=XCI=(12πfC)I=(12π×50×3×10−6)I=(1061)I\begin{array}{r} V_2=X_C I=\left(\frac{1}{2 \pi f C}\right) I \\ =\left(\frac{1}{2 \pi \times 50 \times 3 \times 10^{-6}}\right) I=(1061) I \end{array}Incircuit(T):In circuit (T):V1=IR=(1000)IV2=XCI=(1061)I\begin{aligned} & V_1=I R=(1000) I \\ & V_2=X_C I=(1061) I \end{aligned}ThereforetheTherefore thecorrect options are as under (A) \rightarrowR,S,TR, S, T\quad(B)→(B) \rightarrow Q, R, S, T (C) \rightarrowQorQ orP, Q \quad(D)→(D) \rightarrow Q, R, S, T
