Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I've got this physics problem, I've tried solving it but do not know for sure the steps I took are correct. pls kindly advise and redirect me if I've got it wrong.... thanks

A series RLC circuit with L=11mH, C=2.9uF, and R=4.3ohm is driven by a generator with a max emf of 155V and a variable frequency w (omega)

a) find the resonant frequency (units: rad/s)

answer:

R = V/I = 155/4.3 = 3.6A

XL = Vmax / Imax = 155/36 = 4.3

XL = wL

w = 4.3/11E-3 = 391rad/s

b) find Irmsat resonance when w = 7.6E3 rad/s

XL = 7.6E3 * 11E-3

= 83.6 ohm

XL = V/I

I = V/XL

= 155/83.6

= 1.85A

pls direct me if I am wrong.... appreciate it... I've learned more in this forum than in school...

thanks
