The given circuit has two ideal diodes connected as shown in the figure below. The current flowing through the resistance \(R_1\) will be:
   
1. \(2.5~\text{A}\)
2. \(10.0~\text{A}\)
3. \(1.43~\text{A}\)
4. \(3.13~\text{A}\)

Consider the junction diode as an ideal. The value of current flowing through \(AB\) is: 
   
1. \(10^{-2}~\text{A}\)
2. \(10^{-1}~\text{A}\)
3. \(10^{-3}~\text{A}\)
4. \(0~\text{A}\)
