Capacitively coupled RLC circuits

AI Thread Summary
The discussion focuses on understanding capacitively coupled RLC circuits, specifically how to analyze relevant coefficients like quality factor (QF) and bandwidth. The user seeks organized resources to explain these concepts and how to derive the maximum voltage as a function of frequency for the given circuit setup. They have successfully solved the differential equations for voltage and current but struggle to find comprehensive materials on circuit coupling. Additionally, there is a request for clarification on how the circuit is driven and its resemblance to known coupled RLC circuits. Visual data from measurements of voltage across R1 at various frequencies and coupling capacitor values is also referenced.

Homework Statement


Given a set of two capacitively coupled RLC circuits where each has a capacitor C and they share a coupling capacitor C^{'}.
I'm trying to find nice organized material that will explain the various relevant
coefficients\concepts like QF, bandwidth etc. in relation to the above mentioned setup.
Or how to find the function of the maximal voltage as the function of frequency given a certain setup.

Homework Equations


The Attempt at a Solution



I do know how to solve the differential equations involved and get the voltage and current as the function of time but I can't find good sources that could explain all the aspects of coupling two circuits using a capacitor.

How is the combination circuit driven?

Does the circuit look like any of these coupled RLC circuits? https://www.google.com/search?hl=en...urce=og&sa=N&tab=wi&ei=pnUGU-q6Ec_poATJqYHgAQ

It looks like this:

And the we've measured the voltage on the R_{1} for various frequencies and C^{'} coupling capacitors.

I couldn't see that image.

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
