Question

Four wires of equal length and of resistances 10 ohms each are connected in the form of a square. The equivalent resistance between two opposite corners of the square is

• A. 10 $ohm$
• B. 40$ohm$
• C. 20$ohm$
• D. 10/4$ohm$

Answer 1

Answer: (A)

10 $ohm$

Answer 2

According to the problem, we arrange four resistance as follows

Equivalent resistance $= \frac{20 \times 20}{40} = 10\Omega$
