## How do I measure resistance?

Resistance is measured with the circuit’s power turned off. The ohmmeter sends its own current through the unknown resistance and then measures that current to provide a resistance value readout.

## What is resistance measured by?

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.

## What is used to measure resistance?

An ohmmeter is an electrical instrument that measures electrical resistance (the opposition offered by a substance to the flow of electric current) . Megohmmeters (also a trademarked device Megger) measure large values of resistance. The unit of measurement for resistance is ohms (Ω).

## How do you read a 20k ohm meter?

The ohm setting on the multimeter give you the maximum ohm it can measure up to. For example, 2k ( ohm), 20K (0 to 20,000 ohm), 200K (200,000 ohm), 2m (0 to . 002 ohm). If the resistance is greater than the range setting, it will give zero.

2,000,000 ohms

## How do you read a resistance meter?

Set your multimeter to the highest resistance range available. The resistance function is usually denoted by the unit symbol for resistance: the Greek letter omega (Ω), or sometimes by the word “ohms.” Touch the two test probes of your meter together. When you do, the meter should register 0 ohms of resistance.
