Quick Summary

A series ohmmeter is a type of ohmmeter, which is an instrument used to measure electrical resistance. Resistance is measured in ohms. In a series ohmmeter, the resistance being measured is connected in series with the instrument. As the resistance increases, the current flowing through the circuit decreases, and this change in current is used to indicate the resistance value directly. Ohmmeters were first used in 1884. For measuring very high resistances, a megohmmeter (or megger) is used, with its scale graduated in megohms.12
