An ohmmeter is an electrical instrument that measures electrical resistance. Multimeters also function as ohmmeters when in resistance-measuring mode. An ohmmeter applies current to the circuit or component whose resistance is to be measured.

How does a ohmmeter work?

The working principle of Ohmmeter is, when current flow through the circuit or component, the pointer deflects in the meter. When a pointer moves the left side of the meter, it represents a high resistance and responds to low current. The resistive measuring scale is nonlinear in an ohmmeter and the analog multimeter.

What does ohm meter stand for?

Ohmmeter meaning
