Question

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 :-

• A. 3 v
• B. 1 v
• C. 1.5 v
• D. 2 v

Answer 1

Answer: (B)

1 v

Voltage on 50 cm. = $\frac{6}{300}\times$ 50 = 1 volt
