  Capacitor A capacitor is a clever device composed of two metal conductors separated by an insulating material. On an air conditioner, they often look like large, cylindrical batteries with two or three posts sticking out of the top. The main job of capacitors is to store electrons to provide start-up energy for your air conditioner, they build up a charge when electricity runs through them by swapping electrons between the two conductive plates inside. There are many types of capacitors: Electrolytic Capacitor. Mica Capacitor. Paper Capacitor. Film Capacitor . Non-Polarized Capacitor. Ceramic Capacitor. HVAC Capacitor Variable Capacitor HVAC  Capacitor Cost HVAC capacitors typically cost around $170. Prices for professional installation typically range between $120 and $250. Branded units are more expensive, often costing $400 or more. The cost is determined by the brand, model, voltage, and labor required for installation. The capacitor’s function is to store energy. As the...

  How to Connect a Protection Diode in a Circuit A   protection diode   is used in a circuit so that current will not flow in the reverse direction in the circuit. Because a diode only allows current to flow in one direction in a circuit but not the other, it can protect components in a circuit that are sensitive to current that flows through them in the wrong direction. A protection diode is connected in a circuit by placing the diode in series with the circuitry that is to be protected. For example, in this small project, we're going to connect the protection diode in series with an LED. An LED is pretty sensitive to current in the reverse direction. It can only handle a certain amount of current in the wrong direction. If enough reverse voltage drops across the LED, the LED will break down and allow current to flow through it in the reverse direction, which can cause the LED to be permanently damaged.
