Flashcards

What is an electrode in an x-ray tube?

A component within the x-ray tube that carries an electric current.

What is the cathode's function in an x-ray tube?

The cathode is the negatively charged electrode in the x-ray tube, responsible for emitting electrons.

What is the x-ray tube's external structure?

The support structure, protective housing, and glass or metal enclosure make up the exterior of the x-ray tube.

What comprises the x-ray tube's internal structure?

The anode and cathode are the key internal components of the x-ray tube.
