Using capacitors to regulate the voltage in electrical networks

Capacitors are made within a given tolerance. The IEEE standard allows reactive power to range between 100% and 110% when applied at rated sinusoidal voltage and frequency (at 25 C case and internal temperature) (IEEE Std. 18-2002). In practice, most units are from +0.5% to +4.0%, and a given batch is normally very uniform. ...

Understanding Chip Capacitors

When voltage is applied to a capacitor, a charging current will flow; this current will delay the buildup of the full applied voltage generating a time displacement of the alternating voltage behind the current. In a "no-loss" perfect capacitor, the phase difference between voltage and current would be exactly 90°. In a real
