Question

a wire has a resistance of 12 ohms. if it is bent in from of a circle. the effective resistance between the two points on any diameter is equal to

Answer 1

Answer:

Explanation:

If the wire is bent in form of circle wire above and below diameter will have resistance equally divided among them,that is 6 ohms.These 2 resistances will be in parallel combination.

Hence, effective resistance=(6*6)/(6+6)=3ohms

Hope you understood
