Question

Name the unit of electrical resistance and resistivity.

Answer 1

Electrical resistance is the hindrance to the flow of current. The unit of electrical resistance is ohm ($\Omega$) which is defined as volt per ampere.

Resistivity is the measure of resistance of a given size of a specific material to electric conduction. The SI unit of electrical resistivity is $ohm-metre$ ($\Omega m$). It is commonly represented by the Greek letter $\rho$.
