Network Theory (19EC33)
Source Transformation
Key Points
1. Source Transformation is applicable to Practical sources only.
2. Ignore the resistors that are connected across ideal voltage sources.
3. Ignore the resistors that are connected in series with ideal Current sources.
4. While converting practical current source into practical voltage source, polarity of voltage
source is always positive terminal at the arrow head and negative terminal at the other
side.
5. While converting practical voltage source into practical current source, polarity of current
source i.e., arrow head of current source must be indicated at the positive terminal of the
voltage source.

Source Transformation
Procedure to simplify the electrical networks/Circuits
1. Identify the load element, remove the load element and name the load terminals as A and B
or X and Y etc.
2. Reduce the ideal voltage sources, that are connected in series.
3. Reduce the ideal current sources, that are connected in parallel.
4. Apply Source transformation.
5. Apply Source shifting.
6. Repeat the steps 2 to 5 until simplified form is obtained between the load terminals.
7. Connect the load element and find the load current or load voltage or power delivered or
absorbed by the load element.
