How to calculate leakage resistance of capacitor?

Question

i have calculated the unknown capacitance using simple capacitance bridge. now what is the formula to calculate the leakage resistance of unknown capacitor?

Answer 1

You can't calculate it, but you can measure it.

You will need a voltage supply and a sensitive ammeter. Apply the rated voltage to the diode and measure the current via the ammeter.

Answer 2

Place it in a DC circuit as a resistance in series a high resistance . Measure the voltage across the resistor. Your power supply needs to be clean DC ,because all AC will be measured leakage.
