When the switch is first closed, the voltage across the capacitor (which we were told was fully discharged) is zero volts; thus, it first behaves as though it were a short-circuit. Over time, the capacitor voltage will rise to equal battery voltage, ending in a condition where the capacitor behaves as an open-circuit.
A weak air conditioner capacitor can cause your air conditioning system to consume a lot of electricity so you end up with bigger energy bills every month. Moreover, a bad capacitor can affect the overall performance of your system and shorten its life. turbo capacitor fits in almost all types of air conditioning system, and since it is designed to run on higher voltages, your unit is protected from voltage fluctuations. Moreover, if your turbo capacitor becomes weak, you can always adjust its capacity and prolong its lifespan.
