How long does it take for energy to propagate in a circuit?

The premise In a recent video by the pop-sci channel Veritasium, the concept of the flow of electricity and energy transmission in a circuit was discussed. In that video a thought experiment is presented, as seen below. The question is: after the…

Extend classic transistor flip-flop to an n-state flip-flop?

There is the classic flip-flop using two transistors. I now tried to extend it to be able to store more than 2 states, and thought it'd be interesting to be able to extend it to 3 or an arbitrary number of states and came up with following…

What happens if you connect a galvanometer to an AC source?

What happens if you connect a galvanometer to an AC source? I have seen many answers online along the lines of there not being any deflections as the net average current/net average magnetic field is zero (depends on the site but I won't cite them…

Building a space heater

I'm building a space heater, not for continuous use, but just as an experiment. I made a nichrome wire coil that's 3.5 Ω and a fan that blows on it so hot air comes out of the other side of the tube. Everything is enclosed and both electrically and…

Measuring length of two wires inside copper with a TDR

I have a cable as in the drawing. The black parts are insulators and the brown parts are copper, so there is a big copper cable and inside are two smaller copper cables. When the big copper cable is tied to ground I can use a time domain…

Subtleties with LTSpice's Arbitrary Sources

Here's my setup: I'm trying to emulate the circuit to the right with the one on the left. That is, the one on the right is a pre-charged capacitor (node3) being discharged to its capacitor pair via a resistor (at this point, I'm asking about…

Can a 'superconductor battery' , theoretically at least, last forever? Even if it is being used?

One of the amazing 'killer apps' of a cheap, non-toxic, high-temperature superconductor is storing electrical energy in a large current that loops around indefinitely. If this could be scaled down, it could result in a 'superconductor battery' for…
