If they were not sealed, then you could put items in a vacuum chamber. Maybe that could be as simple as a plastic bag and a vacuum cleaner.

SPICE simulates circuits with discrete time steps of dt, that it adaptively selects. If two 500nF capacitors in series = 250nF, are...

Mineral exploration is multidimensional. You need petrology, geochemical, and structural geology, with geomorphology, to identify...

This would not be the first time that ChatGPT followed a thread on a forum, quoting earlier posts back at a participant.

Step rise time, tr = 1 ps. Total circuit resistance, R2 = 1 pΩ. Initial charge current, I = 250 kA. Those are quite unreal values for a...

In your sim you added R2. This is perfectly reasonable to do, but it is no longer the circuit that the argument is about. Once you add...

Welcome to PF. An impossible situation has been hypothesised. If V1 is an instant step function, then it must instantly charge the two...

Correct. Honey is a supersaturated solution of glucose in fructose, with some other minor compounds. Glucose crystals form initially, as...

If you stir in sufficient sugar, to saturate hot coffee, then you must expect to initially add more solid sugar than is needed, or it...

Because a common ground connection protects the insulation, by preventing overvoltage, that might break it down.

The arrow must represent a conventional current source, or there could be no potential difference between the points A and B..

Is the coffee problem different to stirring paint in an open can ?

Maybe, you need a semicircular plate, attached to a rod that is on the axis of the circle. Push it down, rotate the stick and lift it up...

It comes down to the two different meanings of the term "vector", which in computing, can refer to both a 1D array of many elements, or...

We cannot take our hard-won knowledge with us when we go, so we entrust it to PF, to pass on. We leave it here so google can index it...
