The capacitor has no resistance which your direct current ohm meter can show.
i think we ask that the same as me....
Turn off the supply before using the ohmmeter,it will damaged your ohmmeter when supply is present.

Because an ohmmeter works by putting a potential difference (voltage) across a load and measuring the resulting current (the current will be inversely proportionate to the resistance). In a live circuit there is already current flowing through the load so (at best) the reading will be inaccurate, at worst the meter will be damaged.
A continuity test is a simple test, used to determine whether there is a break in a circuit. This can be done, for example, using an ohmmeter which passes current through the circuit from its internal battery -a deflection (analogue meter) or a '000' reading (digital meter) indicates that there is continuity. A continuity test MUST NOT be performed on an energised circuit, as this will likely damage the ohmmeter and present a shock hazard to the user.
You almost NEVER do. 1) The circuit should be off and/or disconnected when using an ohmmeter. 2) It should be in parallel with the component as far as the rest of the circuit is concerned, but alone in series with the device its measuring.
You have an open circuit.
This is false. A zero reading is what you get when you press the probes of themeter together with nothing between them, to make sure the meter is working.That's about as closed as the circuit under test can get.
None.AnswerIt depends! A capacitor is an open circuit, yet a.c. current flows quite readily. And d.c. current will flow for a very short period of time.
If is being used as an ohmmeter it usually means an open circuit. A switch may be open, or a wire is broken (not a short circuit)
Depending on the voltage, make sure to be safe, but I don't think that it is too bad, although it does depend on the circuit
An ohmmeter is connected in parallel to a resistor. Be sure that there is no power in the circuit when testing.

An Ohmmeter.

When the positive lead is at point "P" which is the base and the negative lead is at either of points "N" which is either the emitter or the collector, then the ohmmeter should have a very low reading or reads short circuit. Also, when the negative lead is at point "P" and the positive lead is at either points "N", then the ohmmeter should have an infinite reading when the meg ohm range.
check the circuit with a voltmeter to make sure the circuit is not powered
