The graphs below show the phasors $\Delta$Vmax and Imax for five RLC series circuits.The solid arrows represent the voltage phasors, $\Delta$V, and the dashed arrows represent the current phasors, Imax.The graph which represents a circuit where the inductive reactance is greater than the capacitive reactance is:

Question

Quizplus · Accepted Answer

In a series RLC circuit, the capacitive reactance (Xc) and inductive reactance (Xl) add up to form the total reactance (X). If Xl>Xc, then the circuit is more inductive and the phase angle between the voltage and current will be positive. This is represented in graph B where the current phasor (dashed arrow) leads the voltage phasor (solid arrow) by a positive angle. In contrast, in graph A, Xc>Xl and the circuit is more capacitive, resulting in a negative phase angle. Graphs C, D, and E represent circuits where Xl=Xc, resulting in a phase angle of zero degrees.
