Undergrad Find Inductance and Capacitance
Okay guys, I think I might understand it. Because I'm given the maximum potential energy of the capacitor, I can use what shankar gave me: U of inductor = 1/2 [ L I(t)2 ] U of capacitor = 1/2 [ Q(t)2 / C] U total = 1/2 [ L I(t)2 ] + 1/2 [ Q(t)2 / C ] = the sum of the individual...- MulatuOyarta

Undergrad Find Inductance and Capacitance
The problem with that is I don't know R or V. In fact, a pure LC circuit doesn't have an R... because it has no resistors.- MulatuOyarta

Undergrad Find Inductance and Capacitance
I have a new question. After reading the article, I am wondering whether the Q-factor they talk about here is the same as the Q in q = Qcos(wt) i = -wQsin(wt) because I thought that "Q" represented the maximum charge of the capacitor. Additionally, if this Q-factor is the same as the Q in...- MulatuOyarta

Undergrad Find Inductance and Capacitance
Well, I already did the f= w/2(pie) = 1/2(pie)((LC)^(1/2)). What puzzles me is how you find L & C after you do this. You see, I thought that somehow if I use i = -wQsin(wt) & q = Qcos(wt), I'd be able to do it. Because I'm told that the maximum current must be a certain value "I", I can say...- MulatuOyarta

Undergrad Find Inductance and Capacitance
Hello, I need to construct an AM radio's RC circuit that: 1. resonates to frequency f= 580 Hz 2. has a maximum current of I = 0.2 A 3. the capacitor has a maximum potential energy U = 2 x 10^-5 I need to find: The inductance and capacitance (L & C) of this RC circuit. Please help...- MulatuOyarta
