Source Transformation

It is possible to convert voltage sources to current sources (or vice versa) if they have the same V-I characteristics.

Plot the V-I characteristics for the following two circuits:

Thus, the two circuits are equal if they satisfies the following condition:

Transformation from Voltage Source to Current Source
