A run capacitor is an electrical component that is used to start and run electric motors. It is typically connected in parallel with the motor’s windings and provides a boost of voltage to the motor when it is starting up. Run capacitors can also help to improve the motor’s efficiency and reduce its operating temperature.
There are a few different ways to test a run capacitor. One common method is to use a multimeter to measure the capacitance of the capacitor. Another method is to use a capacitor tester, which is a specialized tool that can test the capacitance and other characteristics of a capacitor.
