Three ideal diodes are connected to the battery as shown in the circuit. The current supplied by the battery is:

                         
1. zero
2. \(4~\text{A}\)
3. \(2~\text{A}\)
4. \(6~\text{A}\)

The current through an ideal p-n junction diode shown in the circuit will be:

1.  5 A
2.  0.2 A 
3.  0.6 A
4.  zero

In the given figure, the potential difference between \(A\) and \(B\) is:
