8.2: Capacitance and Capacitors
Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series. In contrast, when capacitors are placed in series, it is as if the plate distance has increased, thus decreasing capacitance.

Capacitance in AC Circuits
A bleed resistor, or "bleeder" resistor is placed across a capacitor to help safely discharge it when the supply voltage is removed. If the load resistance is very high, it can take seconds or even minutes for the capacitor''s terminal voltage to quickly discharge down to a safe level reducing the risk of electric shock.

Resistor Capacitance | Resistor Fundamentals | Resistor Guide
Capacitors and Resistors. Electrical loads can be divided into two types: real (or resistive) loads and reactive loads. Real loads are used to convert electrical power into heat. An ideal resistor is a purely resistive load, which means that all the electrical power applied to the resistor is dissipated as heat.

POWER FACTOR CORRECTION – Applied Industrial Electricity
Since we know that the (uncorrected) reactive power is 119.998 VAR (inductive), we need to calculate the correct capacitor size to produce the same quantity of (capacitive) reactive power. Since this capacitor will be directly in parallel with the source (of known voltage), we''ll use the power formula which starts from voltage and reactance:
