How to construct a differential equation from this RLC circuit?
Just so you have my approach to consider, as well. (I know you've already selected an answer.) Here's the redrawn schematic which I prefer:

Kirchoff's Law Problem
You have four relatively obvious current loops that could use KVL. That's all you need for mesh analysis. (You don't need to include any KCL statements for the nodes.)

How do you derive an expression for the output voltage of a ladder network of N sections?
simulate this circuit – Schematic created using CircuitLab
It's the case that \$R_i=\frac{2R\left(R+R_{i-1}\right)}{3R+R_{i-1}}\$, where \$R_{i-1}\$ is the prior source impedance leading up to sect …

Dividing in Polar form
The Photon probably gave you a way too terse answer. But it's correct, just the same. I'll provide a way too long answer. (tl;dr)
Simplistic Geometric Approach
It's best to think of a magnitude (the l …

Why is a linear passive circuit stable, i.e. why does its impulse response approach zero ove...
I suspect the problem may arrive from the requirement of an impossible domain for passive component values. Your characteristic equation breaks down (as I'm sure you already know) into: \$\left(s+1\ri …

RL circuit unit impulse response
It's not complicated. You have two unknown voltage nodes:

Note that I've made the two legs independent of each other, because they ar …

Solving an RL Circuit with an Inductor in Parallel to Resistor-Inductor in Series
I had mentioned that I'd probably take a different approach than user600016's approach, using KCL instead of KVL. Both work for me, but I'm usually more comfortable with KCL as I tend to make fewer er …

Flyback Circuits
Yes, diodes are used in circuits to discharge energy stored on capacitors. It's an entirely different circumstance, though.
Inductors will reverse their voltage when discharging energy and if all the …

Nodal analysis on AC RCL Circuit (I'm confused)
Assuming \$f=60\:\textrm{Hz}\$ and using the included schematic editor:

From this, I get:

Source-free, under-damped, parallel RLC with 2 intial conditions
Just to be complete:
simulate this circuit – Schematic created using CircuitLab
I gather that's the circuit. And you'd like an expression for \$V_{\left(t\right)}\$ and \$I_{L\left(t\right)}\$ …

Electrons inside an LC Circuit
My main question is how the overcharge from the one plate can create
an overcharge on the other.
I think I understand your question. The initial conditions are with the capacitor fully charged …

Query on writing KVL equation for an RL circuit
I'd use KCL (not KVL) with the bottom node "grounded" and the top node as \$V\$:
$$\frac{V}{R}+\frac1{L}\int V\:\text{d}t=0\:\text{A}$$
Taking the derivative with respect to time:
$$\begin{align*}\ …

Calculating Differential equation RLC Circuit
Since everyone seems to have been variously confused at different times about your question, let me re-draw and re-phrase it:

Synthesizing an impedance given by transfer function (poles/zeros) using a passive network
With Verbal Kint's contribution, I'll expand on thoughts behind my earlier comment(s).
Notes from: "A Practical Method of Designing RC Active Filters"
I want to start out by reflecting on the TR-50 pa …

How is it possible that an LC Oscillator create a sine wave?
You know the current in the capacitor must be the same as the current in the inductor. Ground the bottom node, for a simple reference point. Then the current into the capacitor from the top mode (whos …
