Question

Consider the figure below. The resistivity of the material of the half ring is ρ.

a) Is this a series or parallel connection between the ends of the half ring?
b) Find the resistance between the ends of the half ring.

Expert Solution

Step 1

The half ring is made of number of resistors arranged in parallel.
The value of resistance of each half ring increases continuously from inner radius to outer radius.
we have resistivity,

$ρ = R \frac{l}{A}$

where R is the resistance

l is the length and A is the area.
