How to Identify Coil or Capacitor in Series Circuit and Calculate Resistance & Reactance?

So i have this assignment that i have a little problem with. The box with the question mark is a series circuit of two components: a resistor in series with either a coil or a capacitor. How should i reach the conclusion whether if its a coil or capacitor?

The other question is, search the series circuit that matches the specified conditions. 

And the last question is, enter also the resistance of the resistor and reactance of the second component (coil/capacitor).

Thankful for all answers!

Hi,

By the given, you can get your impedance through ohm's law. Now the defining factor if its a capacitor or an inductor is through the sign in the rectangular form (x+ jy) of the impedance. I think the rule here is if you graph the voltage and the current, if the voltage leads the current, its an inductor, but if the current leads the voltage, its capacitive.

Hi there Ilir,
Good day! How are you? I hope you're doing fine.

The current is leading the voltage by 70 degrees.

Thus the source impedance looks capacitive.

To match the line impedance, you need an inductive load, or you need an inductor (coil).

The resistance should be 0.684 ohms and the inductor should be [assuming 60 Hz]
4.985 mH, arrived at by simple ohms law and keeping in mind XL=2*pi*f*L
[inductive reactance].

Hope this helps.

Warm Regards,
Justin
