    Figure shows a source of alternating voltage connected to a capacitor and resistor. Which of the following phasor diagrams correctly secrobes the phase relationship between\[{{I}_{c}}\], the current between the source and the capacitor, and\[{{I}_{R}}\], the current in the resistor?  

    A) \[\begin{align}   & \xrightarrow{{{I}_{c}}} \\  & \xrightarrow[{{I}_{R}}]{} \\ \end{align}\]

    B) \[\xleftarrow{{{I}_{C}}}\xrightarrow{{{I}_{R}}}\]

    C)

    D)

    Correct Answer: A

    Solution :

    [a] Since the cpacitor 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].
