Solution

The correct option is B False
  1. Resistance is basically the opposition that is offered by any substance to the flow of electric current.
  2. So for any given substance, it is a fixed quantity.
  3. Whereas Ohm's Law states that V=IR

where V=Voltage across the circuit

I=Current in the circuit

R=Resistance of the substance

Now since resistance is fixed therefore voltage here is proportional to current and not resistance.

Hence, the statement is false.
