Note that the negative sign means that the capacitor is absorbing negative reactive power VARs which is equivalent to stating that the capacitor is supplying reactive power to the external circuit or system. For a three-phase system, multiply Q by 3 to get the total reactive power supplied by the Capacitor. Thank you!
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.
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.
The squiggly thing is a lowercase phi, the cos of that represents the power factor. From impedance of capacitor Zc = 1 jωC Z c = 1 j ω C , then the reactance is Xc = 1 ωC X c = 1 ω C and reactive power is Q = I2X = U2 X = I2 ωC Q = I 2 X = U 2 X = I 2 ω C C = I2 ωQ C = I 2 ω Q
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. The basis for power factor correction. Select RLC in the reference.
