What is the difference between a resistor and a capacitor?

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.

Are capacitors and inductors reactive?

Capacitors and Inductors are reactive. They store power in their fields (electric and magnetic). For 1/4 of the ac waveform, power is consumed by the reactive device as the field is formed. But the next quarter waveform, the electric or magnetic field collapses and energy is returned to the source. Same for last two quarters, but opposite polarity.

What is the difference between reactive power and capacitance?

Thus, we say that reactive power is positive for an inductance and is negative for a capacitance. If a load contains both inductance and capacitance with reactive powers of equal magnitude, the reactive powers cancel. Power surges into and out of capacitances in ac circuits. The average power absorbed by capacitances is zero.
