A wire of length 10 cm is bent in the form of a circle of radius 2 mm. Calculate equivalent resistance along any two diametrically opposite points if total resistance of wire was 4 ohm

The total resistance of 2∏R is 4 Ω.
The two points divide the circle in two semi-circles.
Thus the length of each semi-circle is ∏R.
For equivalent resistance along two diametrically opposite points:
The resistance of ∏R is 2 Ω
The two resistors are in parallel.
Thus,
Equivalent resistance between A and B,
![1 over R subscript p equals 1 half plus 1 half
1 over R subscript p equals 1
