What is the first goal to accomplish in analyzing a complex series-parallel circuit?
For me, the first thing i always do is,
I try as much as possible to reduce the number of resistors
Consider this circuit
It's always good practice to reduce like here, you can combine the resistors of
So now we are left with two resistors instead of three.Got it?
The choice of the resistors is not always the same, it depends on the question!
