Question : Figure shows a source of alternating voltage connected to a capacitor and a resistor. Which of the following phasor diagrams correctly describes the phase relationship between IC, the current between the source and the capacitor and IR, the current in the resistor?

Doubt by Sonali
Solution : Both the capacitor and resistor are connected in series so the same current will pass through each of them as the supply current. Both IC and IR will be in the same phase.
Hence a) option would be the correct option.
