Question

The graphs in List -II show variation of current I (with continuous curve) and Voltage V (with dotted curve) versus time in certain AC in circuit as mentioned in List -I. Match the given AC circuit in List.I with an appropriate plot in List-II

• A. P-2, Q-4, R-3, S-1
• B. P-2, Q-1, R-3, S-4
• C. P-4, Q-3, R-2, S-1
• D. P-4, Q-1, R-2, S-3

Answer 1

The correct option is A P-2, Q-4, R-3, S-1

P – 2

Q – 4

R – 3

S – 1

In series RC circuit, current leads the voltage.

In series LC circuit current and voltage are out of phase.

In series RLC circuit at resonance, current and voltage are in phase.

In series RL circuit, current lags the voltage.
