Does a capacitor consume reactive power?
Now, observe that SinØ will be negative for Capacitor and hence Q = Negative for Capacitor. Which means that Capacitor is not consuming Reactive Power rather it supplies Reactive Power and hence Generator of Reactive Power. For Inductor, SinØ = Positive, therefore Q = Positive, which implies that an Inductor consumes Reactive Power.

Resistor consumes and reactive device stores/sends power to source. The true benefit is when an inductor AND a capacitor are in the circuit. Leading capacitive reactive power is opposite in polarity to lagging inductive reactive power. The capacitor supplies power to the inductor decreasing the reactive power the source has to provide.
