An ohmmeter measures electrical resistance. This is one part of "impedance", that prevents electricity from flowing freely from one part of a circuit to another.
Resistance is measured in "ohms".

What is the difference in series type and shunt type ohmmeter?
In a series type ohmmeter, the current passes through the resistance being measured, while in a shunt type ohmmeter, the current is diverted around the resistance being measured. Series type ohmmeters are usually less accurate but simpler, while shunt type ohmmeters are more accurate but more complex.
What is Difference between ohmmeter and Wheatstone's bridge?
An ohmmeter is a device used to measure the resistance of a component or circuit by passing a current through it and measuring the voltage drop. In contrast, a Wheatstone's bridge is a circuit used to measure an unknown resistance by balancing it against known resistances in a bridge configuration, without passing a current through the unknown resistor. Wheatstone's bridge is more accurate for precise resistance measurements compared to an ohmmeter.
A zero reading on an ohmmeter means the circuit or component is open is this true or false?
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.
What are the precautions to be observed using ohmmeter?
Ensure that the circuit being measured is de-energized and disconnected from any power source. Use the appropriate ohmmeter setting for the expected resistance range. Avoid touching the leads together before taking a measurement to prevent damage to the meter. Make sure to hold the meter leads securely on the circuit components to ensure accurate readings.
Differentiate derived units from supplementary units?
Derived units are units formed by combining base units through mathematical operations, such as area (square meters). Supplementary units are units used alongside base units to form the complete set of units in a system, such as the radian for angles in the International System of Units.
What an ohmmeter measures?
resistance to current flowAn ohmmeter meassures resistance
Is a ohmmeter a pressure gauge?
No. An Ohmmeter measures electrical resistance to the flow of current.
What is the configuration of the ohmmeter?
An ohmmeter is connected in parallel to a resistor. Be sure that there is no power in the circuit when testing.
Should the ohmmeter be connected to the circuit while the power is being applied or only when the circuit is turned off?
Turn off the supply before using the ohmmeter,it will damaged your ohmmeter when supply is present.
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.

What are two familiar mistakes when using an ohmmeter and a voltmeter?
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
What should the ohmmeter read when the lead probes are touched together?
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.
What kind of meter uses its own battery?
