What A low pressure gas filled glass tube which generates a glowing beam between cathode and anode?

Cathode ray.


In cathode ray tube cathode and anode rays travel opposite to each other but they are not neutralized. why?

There is no such thing as anode rays. The cathode rays (aka electron beam) just travels from cathode to anode.


What sub atomic particle is a cathode ray?

Electrons--the cathode is negatively charged, the anode is positively charged.


Difference between rotating anode x ray tube and stationary x ray tube?

A rotating anode promotes cooling between exposures by distributing the intense beam from the cathode over the surface of the anode. A rotating anode tube lasts a lot longer than a stationary x-ray tube.


What is the source of electrons in the x-ray tube?

The cathode of an electron gun.


In the cathode ray tube where do the particles originate?

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.


Why is the x-ray tube considered an inefficient device?

In X-ray tubes, electrons are emitted from a cathode source to a anode target through a process called thermionic emission. Electrons are then accelerated towards the anode target via a potential energy difference between the cathode and anode. The interaction between the accelerated electrons and atoms in the anode target causes the emission of X-ray. Efficiency of the X-ray tube is impaired by the kinetic energy of the accelerated electrons being loss as heat and only 1% of the remaining energy is used to emit X-ray.


Do X-rays originate from the cathode or the anode of an X-ray tube Yes anode are the source but is this where they ORIGINATE from?

X-rays result when high energy electrons slam into stuff, mostly metals. We accelerate electrons by using high voltage. An X-ray tube has high voltage applied between a cathode and an anode. The cathode, from which the electrons originate, is negative, and the anode, which is positive is the "target" for those electrons. The electrons, having been accelerated by the high voltage, "slam into" the anode, and generate the X-rays. The anode is the source of the X-rays.


Is cathode ray tube and electron tube same?

Yes they are the same. A cathode ray tube (CRT) uses an electron gun to "shoot" electrons from the cathode to specific positions on the anode of the CRT.


Where did the electrons from cathode ray come from?

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.


What is the direction of current in picture tube of TV?

A cathode ray tube (CRT) emits light when electrons strike the front of the glass tube that is covered in a phosphor coating. The front of the tube is the anode of the tube. The electrons are fired from the rear of the tube by an electrode called the cathode. The electrons are formed into a beam or ray, hence the name of cathode ray tube. Although the electrons travel from the rear of the tube to the front, or from the cathode to the anode, conventional current actually flows the opposite direction. So, the current, as measured in amps will flow from the anode to the cathode.
