Resonance and Tuning Methods
Fig. 1 shows an air-wound coil and a mechanical tuning capacitor. The induc- tance value of the coil is not changed in this arrangement. Rather, the capacitor is ad- justed to change the resonant frequency of the coil-capacitor combination. At each setting of the capacitor, we will have resonance (canceled reactance) at a different

Power Factor Correction (pfc) Tutorial
In theory capacitors could provide 100% of compensated reactive power required in a circuit, but in practice a power factor correction of between 95% and 98% (0.95 to 0.98) is usually sufficient. So using our coil from example no2 above, what value of capacitor is required to improve the power factor from 0.5 to 0.95.
