The two materials commonly used for “doping” silicon in solid state rectifiers are:
The type of timer that is most convenient, monitors mA and time and terminates when desired mAs is reached:
Positive side of the x-ray tube:
The two structures within an induction motor are:
The electron flow of a solid state diode goes from:
The exposure switch the in the x-ray circuit is known as a:
The area on the anode’s target where x-rays are emitted?
One of the reasons Tungsten is employed as the target material:
In an induction motor, the only part that rotates is:
rotor
If DC current is better for the x-ray tube, why can we not just use DC from the beginning of the x-ray circuit instead of rectifying an AC current?
transformer would not work
to heat the filaments
When radiographing a wedge shaped anatomical structure such as a femur, the thicker portion of the anatomy should be positioned:
under cathode
AC
atomic element that creates electron “holes”
gallium
The anode side of the x-ray tube has how many cables?
2
The collective repulsion of the electron cloud around the cathode that prevents electrons from being emitted from the filament:
As the SID increases, what happens to the heel effect?
decreases
commutator ring
