The SI unit “Ohm” measures:

Question

Accepted Answer

1. The ohm is the SI unit of electrical **resistance**. Its symbol is $\Omega$.

2. By Ohm's law: $V = IR$, so resistance $R = V/I$. This gives units volt per ampere, i.e. $\Omega$.

3. For comparison: current unit is ampere ($A$), potential difference is volt ($V$), capacitance is farad ($F$).

4. Therefore the correct choice is **(c) Electrical Resistance**.
