14. Two points A and B on a ring made of copper wire
divide the length of the wire in the ratio 1 : 5. If the
resistance of the wire used to form the ring is 600
find the equivalent resistance between A and B.
.
​

Answer 1

Answer:

A uniform wire is made in to a circular ring. Equivalent resistance between points A and B on the ring which subtend an angle of 60 degree at the center of the ring is R. Find the equivalent resistance between A and B if the angle is increased to 120 degree.
