Superposition method

I1

4 kohm

3 mA 6 kohm 12 kohm

+

24 V

In this circuit there are two energy sources, a current source and a voltage source. We will determine the value of I1 due to each of the sources independently (with the other source removed) and then add the results.

First let us determine I1 with only the current source present. We short circuit the voltage source (to make its voltage zero). The resulting circuit is as shown hereunder :

I1

4 kohm

3 mA 6 kohm 12 kohm

This can further be simplified by noting that 4 kohm ...

#### Solution Summary

The problem has been solved using superposition method as well as nodal voltage method.
