Question

Four wires of equal length and resistance $10\Omega$ each are connected in the form of a square. Find the equivalent resistance between any two opposite corners of the square.

• A. $40\Omega$
• B. $10\Omega$
• C. $5\Omega$
• D. $20\Omega$

Answer 1

The correct option is B $10\Omega$

From arrangement we see that the two series combination of two $10\Omega$ resistance are in parallel.

On calculating the equivalent resistance we get $10\Omega$.

Answer-(B)
