#### Solution Preview

1.
As source current, Is = 10 mA, this will be distributed into two branches of 2.2 k-Ohm and 1.2 k-Ohm resistors. Hence, current through the diode will be of the order of a mA.
Hence, potential difference across diode can be assumed
Vd = 0.53 V (From references, for Id = 1 mA)

Let us assume current through 2.2 k-Ohm = I1, and that through diode and 1.2 k-Ohm = I2

I1 + I2 = 10mA == 10*10^(-3) A -------(1)

Let us assume potential at junction ...

#### Solution Summary

This solution addressing two problems, explaining estimation of current through a diode and potential difference across it's two ends.
