How capacitors are tested?

Answer 1

first you need a analog multimeter. put in your meter in the ohm section x10. then remove the cap in the ckt and discharge that. then connect the multimeter -ve probe to the cap +ve terminal and connect the other terminals.the needle comes to low value then com to infinity, remove the probs then connect multimeters -ve prob to the cap -ve terminal that time look carefully the meter's needle comes to the one value and go back to the infinity that the low value is capacitors equivalent resistance value. the cap is 1000uf the equivalent resistance value is around 15 at x10 .the cap is 100uf the equivalent resistance value is around 15 at x100

Answer 2

Capacitors are tested by different ways .

1.Test a Capacitor with an Ohmmeter of a Multimeter

2.Test a Capacitor with a Multimeter in the Capacitance Setting

3.Test a Capacitor with a Voltmeter

Answer 3

With a DVM or voltmeter that has a function included for testing capacitors. You can test by other means but it is less accurate than a dedicated test function.
