Question

A metallic wire of resistance 20 ohm is bent to form a square. The reistance between the two diagonal points will be:
a)40 ohms
b)10 ohms
c)5 ohms
d)20 ohms

Answer 1

Answer:

Since the wire is bend in form of the square and we know that sides of square are equal so each side will have same resistance i.e 5 ohm. Now if we make diagonal two faces in each side of the diagonal will have two sides and resistance will be 10 ohm. As shown below. Hence equivalent resistance is 5 ohm.

Answer 2

Explanation:

Hope this helps you with your question :-)
