Question

I need some serious help with a problem that is so hard I concidered dropping out of school, getting a job at Arby's, punching my manager, getting fired, joining army, flunking the physical, and going back to college.

Thank you for your efforts!

An AC source powers a circuit containing a resistor, a capacitor, and an inductor as shown. If the inductance is 1 H, the capacitance is 1 F, and the resistance 1 Q, find the impedance Zaf, across ab. omega = 1.25 Hz and omega0 = 1/LC = 1Hz. Answer in units of ohm

Explanation / Answer

apply damping frequency W^2 = wo^2 -(R/2L)^2

R/2L)^2 = 1.25^2-1

R/2L = 0.5625

R = 0.5625*2*1

R = 1.125 ohms

so Impedence Z = Rab = 1.125 ohms
