Quick Summary

A parallel ohmmeter is an instrument used to measure electrical resistance, which is quantified in ohms. In a parallel ohmmeter configuration, the instrument draws more current as the resistance being measured increases. This contrasts with a series ohmmeter, where current decreases as resistance rises. A parallel circuit, by definition, offers multiple paths for electrical current to flow, and the voltage across each branch remains the same. An ohm-ammeter is a device that combines the functions of both an ohmmeter and an ammeter.123

ohmmeter
If in parallel (parallel ohmmeter), the instrument will draw more current as resistance increases. If in series (series ohmmeter), current will decrease as resistance rises. Ratio meters measure the ratio of the voltage across the resistance to the current flowing through it. For high resistances, the scale is…
