Consider the two diode circuit as shown in the figure below. D1 & D2 are identical except their area, A1 is the area of D1 & A2 is the area of D2. Then the value of current passing through D1 is:
1
\(\frac{{{I_{in}}}}{{1 - \frac{{{A_1}}}{{{A_2}}}}}\)
2
\(\frac{{{I_{in}}}}{{1 + \frac{{{A_2}}}{{{A_1}}}}}\)
3
\(\frac{{{I_{in}}}}{{1 + \frac{{{A_1}}}{{{A_2}}}}}\)
4
\(\frac{{{I_{in}}}}{{1 - \frac{{{A_2}}}{{{A_1}}}}}\)
