Question

a wire of 4 ohms is bent in the form of a closed circle. what will be the effective resistance between two points at the ends of any diameter of the circle?

Answer 1

HEYA MATE,

HERE IS UR ANSWER.

Thanks for asking this question.

Resistance of wire is 4 ohms

Since, you bent wire in cirlce resitance between two halfs of circle will become half, both resitance are in parellel.

1/R = 1/R1 + 1/R2

1/R = 1/(4/2) + 1/(4/2)

1/R = 1/2 + 1/2

1/R = 1

R = 1 Ohms

I HOPE IT HELPS U.
