Physics - Modern Physics Question with Solution | TestHub

In an X-ray tube, electrons emitted from a filament (cathode) carrying current I hit a target (anode) at a distance d from the cathode. The target is kept at a potential V higher than the cathode resulting in emission of continuous and characteristic X -rays. If the filament current I is decreased to $\frac{I}{2}$, the potential difference V is increased to 2 V , and the separation distance d is reduced to $\frac{d}{2}$, then
