What is the effect of increasing the tube current in an X-ray tube on beam intensity?.
- A.It decreases beam intensity.
- B.It increases beam intensity.
- C.It has no effect on beam intensity.
- D.It causes beam intensity to fluctuate.
Model answer
What a good answer should say
- It increases beam intensity.
Explanation
Why this works
Increasing the tube current in an X-ray tube increases the number of electrons available to produce X-rays, thereby increasing the intensity of the X-ray beam.
