A battery of 10 V and negligible internal resistance is connected across the diagonally opposite corners of a cubical network consisting of 12 resistors each of resistance (as shown in the figure). The total current in the network is:
The current in the branch AB in the given network is:
1. 5/8 A
2. 5/2 A
3. 15/8 A
4. 3/2 A
