Source transformation

Source transformation

Another method of solving and simplifying a circuit is source transformation. Transforming a current source to voltage source by replacing the position of the resistor or the impedance of a circuit and vice-versa. These transformations are useful for solving circuits. It will explain the importance of source transformation and it will explain how to use these conceptual tools for solving circuits.

By using simply the formula of ohm’s law we can transform the circuit

                                                 V=IZ         or        V=IR

                                                 I=V/Z        or        I=V/R

Sample problem:

                      find the current across R4

                     Equivalent circuit that we transform      
                                   by using source transformation:

                                             

                                     I=V/R1    I=50/25     I=2A

                      We can solve our I R4 by using current division.

                    The current flowing in I R4 = 0.2267
