Potentiometer

A 6 volt battery is connected to the terminals of a three metre long wire of uniform thickness and resistance of 100 ohm. The difference of potential between two points on the wire separated by a distance of 50 cm will be

Show answer and solution

Answer: (c)

$k = \frac{6}{3} = 2\ \text{V/m}$ .
$V = 2 \times 0.5 = 1\ \text{V}$ .
So the answer is (c) 1 volt.
