If your capacitor doesnt hold a charge anymore, then it needs to be replaced. It's just that simple! Some online parallel plate capacitance calculator shows about 6pF for that inch of length at a plate separation of 1mm (which is huge).The cling-wrap nowadays is PVC (dielectric constant of 4) and 0.5mils (0.012mm) or less thick, which will bring your capacitance/inch (at 3/4" width) in the order of 1nF. Your email address will not be published. To place a multimeter in Relative mode for capacitance, leave the test leads open and press the REL button.
