ohm's law -physical condition remaining same, the potential difference is directly proportional to the current flowing in the circuit.
Variable resistance - A resister of which the ohmic resistance value can be adjusted either mechanically or electronically.

At any fixed temperature the potential difference is directly proportional to currect through the circuit.
Variable resistance is that resistance whose resistance value can be changed either electronically or physically.
