Question :
Figure shows a potentiometer circuit for comparison of two resistances. The balance point with a standard resistor R = 10.0 Ω is found to be 58.3 cm, while that with the unknown resistance X is 68.5 cm. Determine the value of X.
Isn't the question wrong?
I've searched for it everywhere, but didn't get the correct solution.
i[/COLOR]R/iX = l1/l2
So, R/X = l1/l2
How can the current passing through X be equal to that passing through R?
