3 ways of transient processes, in LRC circuits

AI Thread Summary
The discussion centers on understanding transient processes in RLC circuits, specifically the three types defined by their damping factors: critical, underdamped, and overdamped. The participant shares their experience of observing these transients using an oscilloscope, expressing a desire to replicate the observation with different RLC values. They seek guidance on parameters to visualize all three transient responses in a single circuit setup. Emphasis is placed on the importance of the damping factor in determining the circuit's step response and the challenge of detecting oscillations at high frequencies like 50kHz. The conversation highlights the need for practical component values to effectively demonstrate these transient behaviors.

Hello!

For those that were with me at signals, I passed the exam, but barley. 10,5 points out 20. Going to cancel that exam and do it again when I have the chance.

But anyway, back to the topic.

I am trying to get the intuition for transient processes in RLC circuits. I was taught that 3 exist, each of them represented by different solutions from differential equation.

When I connected an oscilloscope in National instruments, to a RLC circuit, when I turned on the circuit, I saw the transient process. It was like magic to me.

Can anybody give me good parameters, or a guide so I can see all 3 transient processes in the same circuit but with various values for RLC?

Thanks

will determine the RLC circuit's step response. I don't know what component values you have lying around, but use what you've got to and solve for the critical damped case (ζ = 1), underdamped case (ζ < 1) and overdamped case (ζ > 1)?

I wanted nice values in relation to frequency, because, oscillations and transients are not very easy to spot at 50kHz.

Guess I will figure them out of that formula, thanks.
 
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
