Students should remember that the terminals between which the equivalent
resistance has to be calculated have to be kept intact in the transformation
process.
Example 2.37 Calculate the current, I supplied by the battery in the circuit
shown in Fig. 2.129.
Figure 2.129
Solution:
Instead of applying Kirchhoff’s laws and writing the loop equations, we will
convert the delta between ABC or BCD into equivalent star and then make
simplifications to calculate I as
