An ohmmeter is connected in parallel to a resistor. Be sure that there is no power in the circuit when testing.
The main rule to be followed when using an ohmmeter is to have the circuit under test de energized from the power source.
Assuming the red lead of the ohmmeter is more positive than the black lead, then checking the impedance of the diode with the ohmmeter, in both directions, will identify the cathode as the black lead when the measured impedance is low. This, however, will only work if the voltage developed by the ohmmeter is greater than the forward bias voltage of the diode, typically 0.7 volts.
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.
Maybe, but not sure info would be useful. You can use ohmmeter to check that a tube's filament is intact. Broken/burned-out filament is most likely reason for dead tube.
To determine if a capacitor is defective, use an Ohmmeter of a Multimeter.
Basically, your series and shunt ohmmeters differ in circuit configuration. Your series ohmmeter is configured in a way that your "meter" (which has internal resistance) is connected in series to your "measured resistor" and we all know that those TWO resistances will ADD up causing some sort of inaccuracy. While on the other hand, your shunt ohmmeter is configured in a way wherein your "meter" is connected in PARALLEL to your "measured resistor" that will ease-up the inaccuracy but will only measure resistances ranging from 200 Ohms to 400 Ohms (typically and depending on your configuration).
resistance to current flowAn ohmmeter meassures resistance
No. An Ohmmeter measures electrical resistance to the flow of current.
Turn off the supply before using the ohmmeter,it will damaged your ohmmeter when supply is present.
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.

Voltmeter connect in parallel with the circuit setting on voltmeter highest range first then to lower range. Ohmmeter we need to use the ohmmeter meter setting connect across the resistor
When the lead probes of an ohmmeter are touched together, the ohmmeter should read close to zero ohms, indicating a short circuit or very low resistance between the probes.
Never connect the ohmmeter's leads across a voltage.On an analog meter, adjust the zero before use.Turn your ohmmeter off when not in use, to protect against voltage drain.When your ohmmeter's battery is low, or your meter won't be used for a while, remove the battery to prevent damage to the meter from battery leakage.
