Chapter III. Continuation of Nodal Analysis and Wye-Delta Transformation

As we go through the "Nodal Analysis" topic which includes the KCL and KVL and the SUPERNODE, we come up with a lot of problem solving then we have two method in solving/analyzing the circuit, which is the short cut method and the long way method.

The short cut method,

•  The nodal voltage must be determined.

•   it gives the adjacent of the resistors into voltage.

The long way method, 

• The nodal voltages must be determined.

• The flow current of the current must be assigned.

 

#REMINDERS
     ~ The current leaving is positive, and the current entering is negative.

WYE - DELTA TRANSFORMATION

The wye - delta transform, also written wye-delta and also known by many other names, is a mathematical technique to simplify the analysis of an electrical network.

•  wye    -   Y
• delta    -   Δ

~ I think why the wye-delta transformation are made because usually in a circuit(complicated design) have a form of  Y and Δ in order to get the total resistance.
