Difference Between AC & DC Capacitors
In AC circuits the alternating current periodically changes directions, charging the capacitor in one direction and then the other. As the plates discharge during the change of direction, the capacitor output current alternates in phase with the AC voltage. This is how capacitors are said to "pass" AC.

Capacitors Basics
Timing circuits: Capacitors, in conjunction with resistors, can create precise time delays or oscillations in circuits. This is useful for generating clock signals, timing events, or creating frequency references. Coupling and decoupling: Capacitors allow AC signals to pass through while blocking DC components.
Capacitor in Electronics
Direct Current (DC): When connected to a DC source, a capacitor charges up to the source voltage and then acts as an open circuit. This blocks any further DC current. Alternating Current (AC): With AC, the voltage across the capacitor continuously changes. The capacitor charges and discharges cyclically.

Why do we use capacitors in parallel with DC motors?
Generally a 0.01~0.1uF capacitor is wired across brushed DC motors to reduce radio frequency EMI caused by arcing between the brushes and commutator. Sometimes two capacitors are wired in series, with the center connection going to the case to ''ground'' it at RF frequencies. For best effect the capacitor(s) should be placed on or …
