Resistance is measured in ohms. 1 ohm corresponds to an electrical difference of 1 volt for a current of 1 amp (1 volt / 1 amp).

## What are the units of measurement for resistance?

Resistance is a measure of electrical "friction" when electrons move through a conductor. It is measured in units of Om, a unit denoted by the Greek capital letter Omega (Om).

## What device is used to measure resistance?

An ohmmeter is an electrical device that measures electrical resistance, the resistance to electrical current. Microohmmeters (microohmmeters or microohmmeters) measure low resistance.

## How do you measure resistance?

Resistance is measured in ohms. 1 ohm corresponds to an electrical difference of 1 volt for a current of 1 amp (1 volt / 1 amp). You can determine your electrical differential voltage by taking several measurements on your device. Resistance can be measured with a multimeter, analog or digital ohmmeter.
