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.

What is a dry joint in hollow block work?
The dry joint is hollow block work is called a mortar joint. After the blocks are stacked, they are filled with concrete.
Can lamp work only on ac?
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.
What were the two main problems of using vacuum tubes in computers?
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.
How do you work thyristor?
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.
What are George Stephenson's inventions?
he invented the steam locomotive and a safe work lamp that didn't explode for miners to use in 1815
How does a hollow cathode lamp work and what is its role in analytical chemistry?
A hollow cathode lamp works by passing an electric current through a gas-filled tube with a cathode at its center. The cathode emits light at specific wavelengths when the current is applied. In analytical chemistry, the lamp is used as a light source in instruments like atomic absorption spectrometers to analyze the concentration of elements in a sample based on the light absorption characteristics of the elements.
If the ballast on a fluorescent light blows will the lamp still work?
Typically, if the ballast on a fluorescent light blows, the lamp will not work. The ballast regulates the electrical current to the lamp, so if it is not functioning properly, the lamp will not receive the correct power to light up.
3 things a battery needs to work?
Electrolyte, anode, and cathode.
Who discovered subatomic particles during work with cathode tubes?
j.j. Thompson
Will a lamp work if you disconnect it from the wall outlet?
No, a lamp will not work if you disconnect it from the wall outlet. The outlet provides the electrical power necessary for the lamp to function, so without that connection, the lamp has no source of electricity. Even if the lamp is plugged in but turned off, it still requires a connection to the outlet to operate.
What is a dry joint in hollow block work?
The dry joint is hollow block work is called a mortar joint. After the blocks are stacked, they are filled with concrete.

Lamp, because you need electricity for the lamp to work
You have a 1992 caprice and you can't get your hazard lights to work but your turn signals work fine Please help?
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.
How does a Davy lamp work?
Plug it in plug it in.
Can lamp work only on ac?
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.
Will a lava lamp work better in hot or cold water?
A lava lamp will work better in hot water because the heat helps the wax inside the lamp melt and flow more easily, creating the lava lamp effect. Cold water may make the wax inside the lamp too thick and slow-moving, resulting in a less pronounced lava lamp effect.
How does a potato lamp work?
The potato lamp works because the acid in the potato lights up the light bulb.
