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)
Not every relation is a function. But every function is a relation. Function is just a part of relation.

What is the function of rheostat
Resistance is measured with an ohmmeter. A link is provided to a brief article on the ohmmeter posted at Wikipedia.Note that it is unusual in this day and age to have a device that will measure ohms and nothing else. The ohmmeter is usually included among the functions of a multimeter, and usually a digital multimeter or DMM.
resistance to current flowAn ohmmeter meassures resistance
No. An Ohmmeter measures electrical resistance to the flow of current.
An ohmmeter is connected in parallel to a resistor. Be sure that there is no power in the circuit when testing.
A multimeter, also called a VOM, is an ohmmeter, ammeter, and voltmeter combined in one case. A function knob can be turned to select the type of measurement to be made, such as volts, amps, or ohms. The multimeter's test lead connections to the circuit will depend on whether you are using it as a voltmeter, an ammeter, or an ohmmeter.
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.
The easiest way is to use an Ohmmeter. This function is usually built into most multimeter that can be bought at any hardware store. An Ohmmeter measures the electrical resistance of a material. The lower the number the more conductive that material is. If the Ohm reading is above the maximum reading on the meter then their is infinite resistance which means that the material is not a conductor of electricity.
Remove and test with an ohmmeter Explain how to test with an ohmmeter?
Yes.
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
