The wire XY in the circuit is made of a material of high resistivity and uniform area of cross-section. What is the potential difference between X and 65cm mark in the circuit?

Homework Equations

The Attempt at a Solution

$$\frac{65}{100} \times 2 = 1.3V$$

Is this correct?

 

[Volcano]

i think 2 x 65/165 if not misunderstood, the whole length 165 cm.

 

[looi76]

The length of the wire is 100cm. and on that wire the mark is 65cm. Is my answer correct?

If the high-resistivity wire is just between X and Y, then yes it's 1.3 V.
