Does the apparent focal spot size of a rotating anode tube depend upon the speed of anode rotation?

No, but as the rotation speed decreases, the maximum power loading in the spot decreases, so either the power must be turned down, or the spot made larger.

Why positive rays called canal rays?
Anode Rays are called the canal rays as the cathode used is perforated and the anode rays pass through the holes or canals of The cathode opposite to the anode.
What is anode in electroplanting?
negative electrode
What is the tip called on plus side of battery?
anode
Why shape of cathode and anode is like that in electron gun?
The cathode/anode are shaped the way they are to increase the concentration of electrons going in the proper direction. Basically focusing without losing too many.
Why are cathode electrons attracted to anode?
The force between charges is repulsive between charges with the same sign, and attractive between charges with opposite signs. The cathode is charged negative, and the anode is charged positive. Electrons have a negative charge. So any electron in the neighborhood of a pair of charged electrodes will be repelled by the cathode and attracted to the anode.
What types of anode?
the two types of anode is stationary anode and rotating anode
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 are stationary anode x ray tubes?
An x-ray tube where the anode is held still, rather than rotated as would happen in the rotating anode tube.
The purpose of rotating the X-ray tube target is to?
The x-ray tube target is rotated to reduce wear and tear on the anode and to keep the anode from overheating.
Components of rotating anode x ray tube?
rotating anode 1)During a operation large shaped disc tungsten anode rotate at speed 3000 t0 9000rpm(resolution per minute). 2)A motive force to rotate the anode is given by induction motor.therefore windings of which is housed outside the tube. 3)a design element help to limit power density delivered on the physical focal spot while making a small effective focal spot. 4)with rotating anode,heat is produced during exposure is spread over the large area of anode.thereby increases the heating loading capacity of the tube and allowing high power level are used as a result which produces the x radiation. 5) by increasing the anode voltage x rays which produces the shortest wavelength this is used to therpeutic. by decresing the anode current which produces the longest wavelength this is used for diagnostic process.
In a simple cell the cathode or the anode is more reactive?
Anode(:
Is iron a anode or cathode?
it is an anode
What kind of sign does anode has?
An anode is positive, Cathode is negative. As such, an anode would usually be denoted as + If that is what you meant.
Which electrode in the anode is galvanic cell?
Zinc is the anode.
Why anode and cathode rays do not get neutralized?
There is no such thing as anode rays!!
Name of one electrode and say is positive or negative?
The Cathode is the negative electrode; the anode is the positive electrode
What is common anode?
A Common Anode Means A Negative Terminal Of The Battery.
