Question

What happens to voltage when resistance decreases?

Answer 1

1. Ohm's law states that the voltage across the conductor is directly proportional to the current flowing through it and provided all physical conditions and temperature remain constant.
   $\mathrm{V}=\mathrm{IR}$
   where, $\mathrm{V}$= voltage, $\mathrm{I}$ = current and $\mathrm{R}$= resistance
2. From the equation we can say if the current is constant then the potential difference is directly proportional to the resistance.
   $\mathrm{V}\propto \mathrm{R}$
   where $\mathrm{V}$= voltage and $\mathrm{R}$= resistance
3. If resistance decreases the voltage also decreases.
