How a voltage source in series with the new resistance can be transformed into a source of flow ?

When we apply a method to analyze a series of DC, may be necessary to change the source of flow into voltage source or voltage source into a source flow.

Not any source can be transformed. A voltage source in series with the new resistance can be transformed into a source of flow in parallel with resistance. Instead of a flow in parallel with the resistans transformation can be a source of voltage in series with the resistans. In general, how to change the power source into a source of other types shown in the picture below:

• Example

with the Sources Transformation, Change voltage source in the image below into the source flows!

Answer:

The results shown in the picture below:

• Example 2

with the Sources Transformation, Change flow Source on the images below are a source of tension!
