Hi all,
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 Irms at 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
