Problem: For the AC network shown below, determine the current in branch A-B both in polar and rectangular coordinates by using Thevenin’s Theorem.
Solution:
According to Thevenin’s Theorem, we must build an equivalent scheme:
where RL = R3
We must divide our initial scheme into two different schemes: internal (between points A and B) and external (beyond points A and B).
The equivalent resistance:
The equivalent voltage:
In respect of Kirchhoff’s first law:
According to the equivalent scheme, the current value will be as follows.
In polar coordinates:
In rectangular coordinates:
