Thanks, I have gotten that far since I posted. I have the diff eq as L dq^2/dt +R dq/dt +q/c = 0 I'm solving using the general form ay" + by' +cy = 0 the auxiliary equation is am^2 + bm +c = 0 From what I understand is there are three cases to this solution: 1: Distinct...

Homework Statement Consider an RLC circuit with very large Resistance. a) when t = 0, q(0) = 0 b) When t = TL q(TL) = 2Q(1+e)-1cosh(TL/TC) Where TL and TC are the inductive and capacitive time constants, respectively. Show that the charge as a function of time is given by: q(t) =...

sorry about the formating of the answer. It's my first attempt at using the tools. if it helps B = (-1/2) mu_o sigma v in the j hat direction.

Homework Statement you have an infinite sheet of charge in the xy plane, with surfance charge density \sigma, that is moving with a velocity \vec{}v = v\hat{}i. Show that the magnetic fiel at some location above the plane (x,y,z,) = (x,y,h,) is given by \vec{}B = -(1/2)\muo\sigmav\vec{}...

I'm still going to try it your way SammyS. I'd like to see how it unfolds that way. It's always good to know another way to solve a problem.

Yup it worked out. It's amazing that I worked on that problem for hours without realizing I wrote it down wrong to begin with. Thanks SammyS and ehild.

Thanks Sammy. I'll work on it a little more with your suggestions. Thanks ehild. I don't know why but when I worked it out on my paper, I didn't realize the t/tao. I keep using t/(tao + 1). Such a dumb move on my part. Thanks again.

Homework Statement You have an RC-circuit with emf E, resistance R, and Capacitance C. However, R = R(t) = R_o(t/tao+1)^-1, where R_o is the intitial resistance. Assume that other than the time-dependent resistance, the circuit behaves normally. Homework Equations Show that during...
