The typical hollow cathode lamp consists mainly of a cathode containing the element of interest, an anode, and an inert gas. After application of a potential difference between the cathode and the anode, the gas will accelerate toward the cathode removing its material; a process called sputtering. The element of interest is now in the excited state, and upon its return to the initial non-excited state, it would emit light waves of specific wavelength, that can be studied later.
The dry joint is hollow block work is called a mortar joint. After the blocks are stacked, they are filled with concrete.
Depends. Lamps can certainly be built to work on either AC, or DC, or both. But some lamps, particularly those with electronics in them, either a dimmable lamp, or a fluorescent lamp, may only work with one type of electricity.
Valves, or vacuum tubes, were large, generated tremendous heat, and were prone to failure.Vacuum tubes worked much like transistors, but required a filament to heat the cathode so that electrons could flow through the plate when there were the proper grid voltages for that. If the cathode heater burned out, the cathode would not work, and the tube would need to be replaced. Comparing to a PNP or NPN transistor, the cathode would be equivalent to the emitter, the plate would compare to the base, and the grid would computer to the collector. Comparing to an FET, the cathode would be the source, the grid would compare the the gate, and the plate would compare to the drain.
The thyristor functions in such a way that when the anode voltage is greater than the cathode voltage , it is not triggered but only triggers when a gate signal is applied at the gate of the device.
he invented the steam locomotive and a safe work lamp that didn't explode for miners to use in 1815
Electrolyte, anode, and cathode.
If the ballast on a fluorescent light blows the lamp will not work.

Lamp, because you need electricity for the lamp to work

If your hazard lights don't work but your turn signals do work it could be that your Hazard Lamp Flasher needs to be replaced. Your car has both a "hazard lamp flasher" and a "turn signal lamp flasher". Your "turn signal lamp flasher" is working but your "Hazard Lamp Flasher" may not be working. Buy a new "hazard lamp flasher" and install it. The hazard lamp flasher is located behind the instrument panel to the left of the steering column.

Yes, but the output of the panel will be less than the input to the lamp.
In a cathode ray tube (CRT), the particles, which are electrons, originate at the heated cathode, becoming the so-called cathode rays. The electrons stream off the cathode and rush over to the anode.
The potato lamp works because the acid in the potato lights up the light bulb.
