What electrical charge does the anode carry?

When electrons are released from the heated cathode, they are pulled toward the anode by the high-voltage field. The anode must be positively charged to attract these negatively charged electrons to the tungsten target, where their impact produces X-rays. In dental radiography, the cathode is negative and the anode is connected to the positive terminal, creating the electric potential that drives current. If the anode were negative or neutral, electrons would not be attracted effectively, and X-ray generation would be inefficient or stop. So the anode carries a positive charge.
