What is the electrical charge of the anode in the X-ray tube?

• A. Negative
• B. Positive
• C. Neutral
• D. Ground

Answer: (B)

In X-ray tubes, electrons are emitted from the cathode and accelerated toward the anode by a high voltage. To attract and pull these electrons toward it, the anode must be at a higher electrical potential than the cathode, meaning the anode carries a positive charge. This positive potential is what enables the electrons to strike the target material and produce X-rays. If the anode were negative, electrons would be repelled and X-ray production would drop off dramatically. Grounding serves as a reference point and is connected to the tube housing, but the important factor for operation is the positive potential of the anode relative to the cathode.
