Thanks for the question. please find the answer below:


If the length of a potentiometer wire is increased the balance point will increase.


The balance point would keep increasing if the length of the potentiometer wire would be increased.


A potentiometer is a three-terminal resistor that uses a sliding or rotating contact to form an adjustable voltage divider.

Answer:

I don't know whether I'm correct or not but the balancing length will increase by 4 times .

Explanation:

We know,

E1/E2=L1/L2

IR1/IR2=L1/L2

R1/R2=L1/L2

ρL3/A1 * A2/ρL4=L1/L2

L3/A1 * A2/2L3=L1/L2

A2/A1 * 1/2=L1/L2

If volume is constant,

VL3/VL4*1/2=L1/L2

Solving them ...

L1/L2=1/4

Hence, L2=4L1
