Question

what is the unit of resistance?​

Answer 1

$\red\implies$The SI unit of resistance is ohm

( Ω )

$\red\implies$ It is resistance offered by an object when 1 volt potential difference is applied across it and 1 Ampere of current passes through it.

Answer 2

Explanation:

The unit of the electrical resistance, measured with direct current, is the ohm (abbreviated Ω), named after the German physicist and mathematician Georg Simon Ohm (1789-1854). According to ohm's law, the resistance R is the ratio of the voltage U across a conductor and the current I flowing through it: R = U / I.
