A potentiometer wire has a uniform potential gradient. The specific resistance of the material of the wire is $10^{-7}$ ohm-m, the current passing through it is 0.1 A and its cross-sectional area is $10^{-6} m^2$. What is the value of the potential gradient? |
$10^{-4} Vm^{-1}$ $10^{-6} Vm^{-1}$ $10^{-2} Vm^{-1}$ $10^{-8} Vm^{-1}$ |
$10^{-2} Vm^{-1}$ |
The correct answer is Option (3) → $10^{-2} Vm^{-1}$ |
