[問題] 基本電學消失
[問題] 應考資格、各種國考疑難雜症等，以有正確作法、答案者為主
(不包括書裡的疑問)。若問題如人生規劃、讀書計畫等，無一
定作法、答案者，請用閒聊選項。
最進一直算基本電學歷屆試題但每次算到交流電源複數運算都會卡住
因為我不知道在什麼情形下用極作標直角坐標?

我用重疊電壓源短路
Io=(4+J2)(2-J1)/ (4+J2+2-1J)
=(8-4J+4J2) / (6+J)
=(10)*2/(6+J)
=(20)/6.08∠9.46度
=3.289∠-9.46
Vo=Io*R4歐姆
=(3.289∠-9.46)*4
=13.1578∠-9.46
算到這裡我就發覺13.1578∠-9.46都大於ABCD選項
所以一定是我算錯?
請問我有哪個地方算錯?
