What device is used to measure the resistance of a resistor?

You can use a multi-meter to measure resistance. The specific portion of the meter for measuring resistance is called an ohmmeter.


Is a ohmmeter a pressure gauge?

No. An Ohmmeter measures electrical resistance to the flow of current.


What are the advantage of ohmmeter?

To measure resistance, and to check continuity.


Do you unplug before measuring resistance?

Yes. Measuring resistance involves imposing a small current through a device and measuring the voltage drop. If there were any other source of voltage, the reading would be in error. You could also damage the ohmmeter if there were an external voltage source. You should also take the device out of circuit before measuring it, so as to not bias the results by the resistance of other devices in the circuit. It all depends on the situation, for which you are responsible for evaluating before you start.


Why the resistance of a capacitor is infinite when measures with an ohmmeter?

The typical ohmmeter measures DC resistance by providing DC current and measuring the voltage drop accross the resistor. By definition, the 'ideal' capacitor is an open circuit to DC current and voltage. By definition, an open circuit has infinite resistance. Of course, real-world capacitors are not ideal. They have a very high parallel leakage resistance and a very small series resistance. And, different meters can measure different ranges of resistance. So, you may not get an infinite/overload measurement on some capacitors with some meters. You may get a very high resistance instead. If so, you are not really measuring the resistance of the 'capacitor', but rather that of the imperfections in the component manufactured to be a capacitor. ANSWER: The ohmmeter battery will charge the capacitor in 5 time RC after that it quirts there is no more current flow. Any body that claim to be able to check resistance of a capacitor i just a wannabe

What is ohmmeter?

An ohmmeter is a type of electrical metre that measures electrical resistance. When in resistance-measuring mode, multimeters also operate as ohmmeters. An ohmmeter measures the resistance of a circuit or component by passing electricity through it.

Does the ohmmeter need to be parallel to the load when measuring resistance?

It does not matter, since the ohmmeter needs to be connected to the device in isolated mode. Series or parallel; they are both the same, in this case.

What precuation must be taken when using an ohmmeter?

Be certain the circuit is de-energized and discharged before connecting an ohmmeter.Do not apply power to a circuit while measuring resistance.When you are finished using an ohmmeter, switch it to the OFF position if one is provided and remove the leads from the meter.Always adjust the ohmmeter for 0 (or ∞ in shunt ohmmeter) after you change ranges before making the resistance measurement.


How is resistance measured?

Where do you set the dial when you are measuring resistance on house current?

YOU DO NOT "measure resistance on house current".You never measure resistance of anything that has any path to any source ofpower ... not to a wall outlet, a battery, a windmill, a solar panel, etc. You onlymeasure resistance when all power is REMOVED from the circuit or componentyou're measuring. Then, the range you choose for the ohmmeter depends onthe component or circuit you're measuring, NOT on how it's powered when it'sturned on.
