Methods of Finding Thevenin’s Equivalent Circuit

 We already have discussed 1^st approach in the last blog, if haven’t visited there click here to read the blog.  Let’s now talk about 2^nd approach.

Method 2

When both independent type and dependent type sources are present, use these methods to find Thevenin’s equivalent circuit.

Step 1 − Consider the circuit diagram by opening the terminals with respect to which, Thevenin’s equivalent circuit is to be found.

Step 2 − Find Thevenin’s voltage  V_Th across the open terminals of the above circuit.

Step 3 − Find the short circuit current ISC by shorting the two opened terminals of the above circuit.

Step 4 − Find Thevenin’s resistance  R_Th by using the following formula.

Step 5 – Connect the Thevenin voltage V_Th and Thevenin resistance R_Th in series to create the Thevenin equivalent circuit.

The response is now located in a component that is on the right side of Thevenin’s equivalent circuit.
