Hello everyone,
There this one idea I am confused about.
There is this circuit for example and I am asked to find the complex power of the source.
I get the idea of finding I1, I2, add them and find I by kcl.
I can find Vs by adding (I(0.2 + j0.4) + 240<0)
Then here is my question, to find the power of the source S = VI*.
Why in the solution they directly multiply VI*? Shouldnt they multiply I with a minus sign to make the current enter from the positive terminal
of the voltage source to make it conform with the passive sign convention.
