Question 42/75
Time: 02:45
Year: 2023Subject: Physics
Chapter: Current ElectricityClass: 12

A wire of resistance 10Ω is bent to form a square. The equivalent resistance between two diagonally opposite corners of the square is:

5/2Ω
20/3Ω
10/3Ω
Correct Answer: 5/2Ω

When the wire is bent into a square, each side has R/4 = 2.5Ω. Using symmetry and applying resistance combinations...
