figure, shows a source of alternating voltage connected to a capacitor and a resistor. Which of the following phasor diagrams correctly describes the phase relationshop between `(I_C)` the current between the source and the capacitor and `(I_R)` the current between the source and the resistor?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B

Since the capacitor is connected in series to the resistor, current `(I_C)` from the supply and `(I_R)` through the resistor is in phase as represented by choice (a).
