When discharging the capacitor, only touch the plastic handle of the tool—do not touch any metal parts of the tool or the AC. Test the AC capacitor using a multimeter. After discharging the capacitor, it''s time to test the capacitor using your multimeter. You''ll need a multimeter with a capacitance test setting.
Discharge the capacitor: To ensure safety, use a resistor or other suitable method to discharge the capacitor and remove any stored charge. Connect the multimeter probes: Attach the positive (red) probe to the positive terminal of the capacitor and the negative (black) probe to the negative terminal.
Try 20-lb. bond computer paper which has a 4 mil thickness. Prepare this inexpensive capacitor by interleaving layers of dry paper with aluminum foil, and then immerse the capacitor in oil until the paper gets saturated. One disadvantage to using oil in home-made capacitors is that the tape or glue used to bond the assembly must be oil-resistant.

What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other.
