What is the characteristic charge of the anode side of an X-ray tube?

The characteristic charge of the anode side of an X-ray tube is indeed positive. In the setup of an X-ray tube, electrons are emitted from the cathode and travel towards the anode. The anode is positively charged to attract these electrons, which facilitates the process of X-ray production. When the high-speed electrons collide with the anode material, they interact with the atoms, resulting in the emission of X-rays. The positive charge of the anode is essential for its function, as it ensures that the electrons generated at the cathode move in the correct direction towards the anode, allowing for efficient energy transformation and X-ray generation.
