Where does the direction of electric current flow within an x-ray machine?
Anode to cathode
Target of the anode to the filament of the wire
Filament of the cathode to the target of the anode
None of the above
The correct answer is: Filament of the cathode to the target of the anode
The correct understanding of the flow of electric current within an x-ray machine is that it moves from the filament of the cathode to the target of the anode. In this process, the cathode consists of a filament that, when heated, produces a cloud of electrons around it. Upon applying a potential difference, these electrons are accelerated towards the anode, specifically striking the target area, where x-rays are generated. This flow accounts for the fundamental mechanism of x-ray production, where the kinetic energy of the electrons converts into x-ray photons upon interaction with the anode material. Recognizing this flow of current is crucial for understanding how x-ray machines operate efficiently and safely.
