FAQ:

Q: What is an ESR capacitor tester?

A: An ESR meter is a two-terminal electronic measuring instrument designed and used primarily to measure the equivalent series resistance (ESR) of real capacitors; usually without the need to disconnect the capacitor from the circuit it is connected to.

Q: Do capacitors have a resistance?

A: Since the capacitor is basically a charge storage, there is no such equation as this hence you can say there is no electrical resistance. But if you define resistance by its truest meaning, the capacitor is resistant to low frequencies but allows high frequency currents to pass through.

Q: Do capacitors store current?

A: It stores charges like a battery does but is not as good as a battery holding the charge for much longer time. The current is the rate of flow of charge which can occur when a load is connected across the cap’s terminals. A capacitor won’t store current.

Q: How are capacitors tested?

A: A test that you can do is to see if a capacitor is working as normal is to charge it up with a voltage and then read the voltage across the terminals. If it reads the voltage that you charged it to, then the capacitor is doing its job and can retain voltage across its terminals.
