15.9: Alternating-Current Circuits (Exercise)
15.4 RLC Series Circuits with AC 24. What is the impedance of a series combination of a 50-Ω resistor, a 5.0-μF5.0-μF capacitor, and a 10-μF10-μF capacitor at a frequency of 2.0 kHz? 25. A resistor and capacitor are connected in series across an ac generator.
Coupling Capacitor Voltage Transformers (CCVTs)
In some circumstances, the CVD capacitive reactance can resonate with the magnetizing reactance of the inductive voltage transformer and the compensating reactor cores. This unwanted effect is called ferro-resonance and can give rise to large and damaging voltages across the inductive and capacitive elements.

POWER FACTOR CORRECTION – Applied Industrial Electricity
An 80 µF capacitor will have a capacitive reactance of 33.157 Ω, giving a current of 7.238 amps, and a corresponding reactive power of 1.737 kVAR (for the capacitor only). Since the capacitor''s current is 180 o out of phase from the load''s inductive contribution to current draw, the capacitor''s reactive power will directly subtract from the load''s reactive power, …
