Solution:

Let us convert this circuit into a Thevenin’s equivalent circuit through the

following steps:

open circuit voltage V AB is calculated as

Figure 2.102

Voltage drop across terminals C and D = 2 × 2
= 4 V

Voltage across terminals C and D is the same as the voltage across terminals

A and B since no current is flowing beyond terminals C and D when the load
resistance has been removed.
