Quick Summary

A megohm is a unit of electrical resistance, equivalent to one million ohms. The ohm (\u03a9) is the standard unit for electrical resistance, defined as the resistance of a conductor through which a current of one ampere flows when a potential difference of one volt is applied.12

In electronics, resistance is the property of a circuit that opposes electric current, converting electrical energy into heat. For measuring very high resistances, an instrument called a megohmmeter or "megger" is used, with its scale typically graduated in megohms. The prefix "mega-" signifies a factor of one million (106).234
