Source Transformation

Source transformation is the process of replacing a voltage source vs in series with a resistor R by a current source is in parallel with a resistor R, or vice versa.

Source transformations are easy to perform as long as there is a familiarity with Ohm's law. If there is a voltage source in series with an impedance, it is possible to find the value of the equivalent current source in parallel with the impedance by dividing the value of the voltage source by the value of the impedance. The converse also applies here: if a current source in parallel with an impedance is present, multiplying the value of the current source with the value of the impedance will result in the equivalent voltage source in series with the impedance.

Learnings 
Using Source transformations are easy to perform as long as you have knowledge with Ohm's Law. Just transform a voltage source in series with an impedance to a current source in parallel with the impedance, in AC source transformation is also the same in the DC source transformation.
