How do capacitors work

A capacitor or power cap is a vital electronic component of your car’s audio system. It can supply and store current to the car’s audio amplifier. Keep in mind that the capacitor has three major ports: two are electrical conductors, and the other is dielectric. You see, the dielectric insulates those two electrical conductors.

It is a passive electronic component that has two terminals; its effect is known as capacitance. A capacitor is designed for adding capacitance to a circuit that exits between two electrical conductors in proximity present in a circuit. Capacitors for AC applications are primarily film capacitors, metallized paper capacitors, ceramic capacitors and bipolar electrolytic capacitors. The rated AC load for an AC capacitor is the maximum sinusoidal effective AC current (rms) which may be applied continuously to a capacitor within the specified temperature range. Once the field is built, current can flow normally through the wire. When the switch gets opened, the magnetic field around the coil keeps current flowing in the coil until the field collapses. This current keeps the bulb lit for a period of time even though the switch is open. In other words, an inductor can store energy in its magnetic field ...

Capacitors store energy by accumulating an electric charge on their conductive plates. When a voltage is applied across a capacitor, positive and negative charges build up on the respective plates. This creates an electric field between the plates, with the insulating dielectric preventing charge flow between them. Due to the high cost and proper maintenance of capacitor start motors, a fixed rated (generally 2.5μF to 3.5μF) capacitor is used permanently in motor (which is known as capacitor start capacitor run motors) to overcome this problem.

2. Kirchhoff's voltage law (or loop law) is simply that the sum of all voltages around a loop must be zero: ∑ v = 0 ∑ v = 0. In more intuitive terms, all "used voltage" must be "provided", for example by a power supply, and all "provided voltage" must also be "used up", otherwise charges would constantly accelerate somewhere.
