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.

Factors influencing quality and intensity of xray?
Power of the X-ray tube, voltage applied, current intensity, anticathode type, filters, collimator, tube design, working atmosphere, etc.
How rays can be produce by cathode ray oscilloscope?
A: xray emits from TV, OSCILLOSCOPE and some more instruments due to requirement of hi voltage to see the display
How do you calculate the current in 40W tube light in 230V?
Voltage x Current = Power So Power / voltage = current Now you do the math
In a color television set using a picture tube a high voltage is used to accelerate electron beams to light the screen That voltage is about?
25 thousand volts
How does a choke work in a tube light circuit?
The choke works in conjunction with a starter . When you turn on the light , voltage is applied to the choke, and when the switch opens after a few seconds, it creates a high voltage across the contacts at each end of the tube. This starts the ionization of the gas , which glows. Once ionized, it continues producing light even when the voltage applied is only 120 VAC, the power line voltage.
Factors influencing quality and intensity of xray?
Power of the X-ray tube, voltage applied, current intensity, anticathode type, filters, collimator, tube design, working atmosphere, etc.
Which factor controls the amount of radiation emitted from the xray tube?
mA
The radiation emitted from the xray tube and strikes the patient directly is called?
primary radiation
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 is the maximum amount of leakage radiation that can escape from an xray tube?
1 mGya/hr at 1 meter.
What are the people that do x rays?
They are radiologic technologists, or radiographers for short.
What is the proper method of confirming nasogastric tube placement?
Confirming Nasogastric tube placement must be done through pH testing and xray, not by using the whoosh method.
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
Is vacuum tube a voltage controlled device?
yes, effectively a voltage controlled conductance. (conductance being the reciprocal of resistance)
