What are the SI units of electrical resistance?

1 Answer

The SI (International System of Units) unit of electrical resistance is the ohm, symbolized by the Greek letter "Ω". It is named after Georg Simon Ohm, a German physicist who formulated Ohm's law, which describes the relationship between voltage, current, and resistance in an electrical circuit. One ohm is defined as the resistance between two points in a conductor where a constant potential difference of one volt results in a current of one ampere.
