23 · Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured …
Capacitive Voltage Divider Circuit as an AC Voltage Divider
Consider the two capacitors, C1 and C2 connected in series across an alternating supply of 10 volts. As the two capacitors are in series, the charge Q on them is the same, but the voltage across them will be different and related to their capacitance values, as V = Q/C.. Voltage divider circuits may be constructed from reactive components just as easily as …

Power Factor Improvement Principle and Correction Methods
Power factor can be corrected by connecting a static capacitor in parallel with the load taking lagging reactive power. As a capacitor is generator of reactive power, therefore the lagging reactive power demand of the equipment is locally supplied by the static capacitor. Thus the p.f is improved. This method is same as discussed in the …
