Can anyone expalin me in detail why is it that while calculating total impedance the impedance by resistor and impedance by inductor(or capacitor or both) are added in the form of complex number a+ib rather tha just a+b??

Question

anonymous · Answer

impedance of a resistor is the resistance, the impedance of a capacitor, is $$1/j \omega C$$ so you end up with a complex form, and the impedance of an inductor is $$j \omega L$$which is again in complex form, so when you add them you've got  to add the real part and the complex part. i hope that helps

well why is resistance of a resistor taken in real form and that of capacitor and inductor taken in complex form.why cant the all be real

anonymous · Answer

and as far as i know impedance of a capacitor and inductor are 1/(omega C) and omega L respectively na

i dont know why da impedance of a resistor is taken to be the resistance and why the capacitor and inductor have a complex form, but im sure that the equations ive written for the impedances of the capacitor and inductor are correct, so use those equations to calculate the impedances
