Which of the following transformation is shown below in the given figure?

Right Answer is:

Current transformation

SOLUTION

A practical current source having an ideal current Is in parallel with an internal resistance Rsh can be replaced by a voltage source Vs = I × Rsh in series with an internal resistance as shown in Fig.

A voltage source is equivalent to a current source and vice-versa, if they produce equal values of IL, and VL, when connected to the load RL, They should also provide the same open-circuit voltage and short-circuit current.

If the current source is converted into a voltage source, as in Fig.. we consider the open-circuit voltage equivalence, then

VS = I.Rsh
