Question

A wire of resistance 20 bulb is bent to form a closed square. What is the resistane across the diagonal of the square?​

Answer 1

Answer:

The answer to your question is 5 ohm.

Explanation:

As because,

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.
