Vedclass · Answer

(A) The intensity of an $X-ray$ beam is directly proportional to the number of electrons striking the target per unit time.This number of electrons depends on the rate of thermionic emission from the filament.The rate of thermionic emission is controlled by the filament current.Therefore,increasing the filament current increases the number of electrons emitted,which in turn increases the intensity of the emitted $X-ray$ beam.Thus,the correct option is $A$.

In an $X-ray$ tube,the intensity of the emitted $X-ray$ beam is increased by
