VL and VC are out of phase by π.
4 is lagging 2, thus C and E are incorrect.
Let us now consider some basic applications of phasors to AC circuits.
Consider this diagram. Let us assume that it describes a series circuit containing a resistor, capacitor, and an inductor. The current in the circuit has amplitude, I, as indicated in the figure.
Which of the following choices gives the correct respective labels of the voltage across the resistor, the capacitor and the inductor?
A) V1; V2; V3
B) V1; V2; V4
C) V1; V4; V2
D) V3; V2; V4
E) V3; V4; V2
