A 1.20 kΩ resistor and a 6.8 μF capacitor are connected in series to an AC source. Calculate the impedence of the circuit if the source frequency is a) 60 Hz, b) 60,000 Hz(adsbygoogle = window.adsbygoogle || []).push({});

I think I should this equation:

Vrms = Irms, Z : XL = 2ΠfL : XC = 1 / 2ΠfC

Z = √R2 + ( XL – XC )2 so: Irms = Vrms / Z

My main problem here is I don’t know how to do the equation without a given L. Do I need a given L (in Henry’s) to do the problem, and if I don’t, how else can I do it? Any help appreciated,

Thanks,
