How do you identify a bad capacitor?

A capacitor is a device that stores electrical energy in an electric field. It comprises two conducting plates separated by an insulating material called a dielectric.

When a capacitor is connected to a circuit, it stores energy in the form of an electric field between its plates.

This is how the capacitors can be differentiated and understood as good or bad.
  • One way to tell if a capacitor is bad is to measure its capacitance with a multimeter. If the reading is very low, or if the capacitor is completely discharged, the capacitor is likely bad. 
  • Another way to tell if a capacitor is bad is to look for signs of physical damage, such as leaking electrolytes, bulging or swollen.
