What happens to an x-ray spectrum when the tube voltage is changed?

as you increase current, the number of electrons being produce by the cathode(filament) will also increase.
e.g doubling the current(mA) will double the number of electrons being produced.

∙ 11y agoIf you increase the voltage on an x-ray tube more electrons pass from cathode to anode with higher energy. The resultant x-ray beam penetrates further. The resultant image had more contrast i.e it is more shades of grey than black and white. It is particularly useful for chest x-rays as the ribs are not as marked and you can see the lungs behind the ribs.

What happens when we switch on the tube light does current flow through it or voltage?

What is the voltage of a TV picture tube?
We're talking about high voltage when we talk about the operating voltage of a cathode ray tube (CRT). The operating voltage can vary, as you can imagine. Tens of thousands of volts are not uncommon.
What happens to nutrients in the esophagus?
Nutrients are neither changed nor absorbed in the esophagus. No digestion occurs in this tube that connects the mouth and stomach.
How much voltage required for tube light?
120
Why is neon gas used in voltage stabilizers?
Neon gas has a break-down voltage of about 70 volts. When the gas (in a neon voltage regulator tube) breaks down, the gas glows red. If more voltage is applied (within sensible limits) the voltage drop across the neon VR tube will still be 70 volts. This action by itself could result in a large current flowing in the gas tube and possibly to destroy it, so a resistor is placed in series with the neon VR tube to limit the current. And this is better for the neon tube as well. THUS a neon voltage regulator tube forms a reference voltage which can be used, with clever circuitry, to regulate any voltage. Other gas mixtures are used for other voltages. There are solid-state devices with similar properties.
Who made the beam of electrons in vacuum tube?
This beam of electrons is emited by the cathode under voltage difference.
What is principle of fluorescent tube light how choke gives transient voltage across tube at the time of starting?
11000
How does an emission spectrum of a gas in a discharge tube differ from a white light spectrum?
It differs by that white light spectrum is continuous and consists of light of all wavelengths. Emission spectrum is not continuous. It consists of bright lines at specific wavelengths, with complete darkness between them.
What is x-ray tube voltage?
X-Ray voltage means voltage which is applied across anode & cathode, this is of very high voltage (in KV). This causes a high electric field for the moving of electrons emitted from cathode to anode. One more voltage wrt X-ray tube is filament voltage. Filament voltage with some appropriate current is applied to filament for the emitting of electrons. This current is proportional to the intensity of X-ray radiation generated from the tube. More current through the filament causes permanent damage of filament.
Is vacuum tube a voltage controlled device?
yes, effectively a voltage controlled conductance. (conductance being the reciprocal of resistance)
Where to put the transmission fluid in a 1989 Spectrum?
all automatic fill thru the dipstick tube.
When was the crookes tube invented?
The Crookes tube is a sealed glass tube that exhibits fluorescence in it after voltage is passed through the electrodes inside. It was invented in 1875 by Sir William Crookes.
