In the network shown in the Fig, each resistance is 1 Ω. The effective resistance between A and B is

1. 4/3 Ω
2. 3/2 Ω
3. 7 Ω
4. 8/7 Ω

Correct answer: 4/3 Ω

Solution

The network forms a combination of series and parallel resistances. Simplifying the circuit step by step, the effective resistance between A and B is calculated to be 4/3 Ω.
