Turn off the power to your AC. If you''re testing the blower motor capacitor, turn off the power to your air handler or furnace. If you''re testing the compressor or condenser fan capacitor, turn off the power to your condensing unit. Disconnect the wires going to the capacitor.
The size of the capacitor is determined by the size of the potential output current transient and the allowable input voltage ripple of the design specification. The necessary capacitance needed can often be quite large and therefore Electrolytic Capacitors are often used for bulk capacitance.
A capacitor is a device that stores electrical energy for a short time. Capacitors consist of two metal plates with a material called a dielectric in between. When connected to power, these plates hold opposite electrical charges. Later on, the capacitor can release this energy into the circuit.

The second reason is that ESR is not a constant value with regard to frequency. The ESR varies with frequency due to the skin effect, as well as other effects related to the dielectric characteristics. A related term, called the dissipation factor(DF), is sometimes defined in capacitor datasheets instead of the Q-factor.
Supercapacitors are also known as ultracapacitors or double-layer capacitors. They bridge the gap between capacitors and batteries. Supercapacitors display higher energy density than a conventional capacitor and higher power density than batteries. They have high cyclic stability, high power density, fast charging, and good rate capability.

Capacitor Construction. A capacitor is constructed out of two metal plates, separated by an insulating material called dielectric. The plates are conductive and they are usually made of aluminum, tantalum or other metals, while the dielectric can be made out of any kind of insulating material such as paper, glass, ceramic or anything that obstructs the flow of the current.
Capacitors favor change, whereas inductors oppose change. Capacitors impede low frequencies the most, since low frequency allows them time to become charged and stop the current. Capacitors can be used to filter out low frequencies. For example, a capacitor in series with a sound reproduction system rids it of the 60 Hz hum.

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.
