In a Coolidge tube, electrons strike the target and stop inside it. Does the target get more and more negatively charged as time passes?

When an electron strikes the target in a Coolidge tube, its entire kinetic energy

When a Coolidge tube is operated for some time it becomes hot. Where does the heat come from?

An x-ray tube is operated at 20 kV and the current through the tube is 0*5 mA . Find (a) the number of electrons hitting the target per second, (b) the energy falling on the target per second as the kinetic energy of the electrons and © the cutoff wavelength of the X-rays emitted.

A diode valve is connected to a battery and a load resistance. The filament is heated so that a constant current is obtained in the circuit. As the cathode continuously emits electrons, does it get more and more positively charged?

50% of the X-ray coming from a Coolidge tube is able to pass through a 0.1 mm thick aluminum foil. If the potential difference between the target and the filament is increased, the fraction of the X-ray passing through the same foil will be

In beta decay, an electron (or a positron) is emitted by a nucleus. Does the remaining atom get oppositely charged?

Figure shows the intensity-wavelength relations of X-rays coming from two different Coolidge tube. The solid curve represents the relation for the tube A in which the potential difference between the target and the filament is V_a and the atomic number of the target material is Z_A . These quantities are V_beta and Z_beta for the other tube. Then,

50% of the X-ray coming from a Coolidge tube is able to pass through a 0.1 mm thick aluminum foil. The potential difference between the target and the filament is increased. The thickness of aluminum foil, which will allow 50% of the X-ray to pass through, will be

The electric current in an X-ray tube (from the target to the filament) operating at 40 kV is 10 mA . Assume that on an average, 1% of the total kinetic energy of the electrons hitting the target are converted into X-rays(a) What is the total power emitted as X-rays and (b) how much heat is produced in the target every second?
