How Do Transmission Lines Function as Parallel LC Circuits?

I'm currently doing a lab on pulses in cables. The instructions describe the transmission line as a series of parallel lc circuits that transmit the pulse back and forth along the line, but I'm not sure I understand exactly how it works. I understand how an individual lc circuit works, but I'm unsure about how they are acting together in the transmission line.

Can anyone provide some insight into this?

Cheers,
W. =)

Have you learned about the "Telegrapher's Equations" yet? Here's a link -- your text should have these equations as well:

(note: the wikipedia.org site is not necessarily accurate or stable, especially on more complex technical and Physics-related topics. On this EE topic, it's pretty reliable and stable, especially if you follow the links in it to verify and further your understanding.)

Hello everyone, I’m considering a point charge q that oscillates harmonically about the origin along the z-axis, e.g. $$z_{q}(t)= A\sin(wt)$$ In a strongly simplified / quasi-instantaneous approximation I ignore retardation and take the electric field at the position ##r=(x,y,z)## simply to be the “Coulomb field at the charge’s instantaneous position”: $$E(r,t)=\frac{q}{4\pi\varepsilon_{0}}\frac{r-r_{q}(t)}{||r-r_{q}(t)||^{3}}$$ with $$r_{q}(t)=(0,0,z_{q}(t))$$ (I’m aware this isn’t...
Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
