Hello everybody!
I try to get a result of a complex number arithmetic, but I can't.
I don't want to use scientific calculator, I want to do step by step as described on http://www.allaboutcircuits.com/vol_2/chpt_2/6.html
The example I want to solve is on http://www.allaboutcircuits.com/vol_2/chpt_5/4.html
The problem is with ZL and ZC2 which are in series.
ZL = 245.04<90°
ZC2 = 1768.4<-90°
If I want to add up, I have to convert them to rectangular form.
ZL = 0+j245.04
ZC2 = 0-j1768.4
ZL-C2= 0-j1523.36
And here comes the question: how to convert this back to polar form?
If I follow the rules given on http://www.allaboutcircuits.com/vol_2/chpt_2/5.html I do this:
\(\sqrt{0 square +(-1523.36 square)}\) = 1523.36
From this the polar form would be:
1523.36 < arctan 1523.36/0
However, dividing a number with 0 makes my calculator to give error message. It's ok, because in elementary we learned, that dividing with 0 is foolish.
In the mean time, somehow I have to get the polar form, but how, if division with 0 is impossible?
If you have an idea, and a correct result for common impedance of ZL and ZC2 please let me know!
