LRA 222 Finals Review Questions And Correct Answers



The anode consists of the - Answer target and induction motor



The cathode consists of the - Answer Filaments and focusing cup



The motor that rotates the anode works by the principal of - Answer mutual induction



When the anode is rotated the focal spot becomes a focal - Answer track



The focusing cup is able to keep the electrons together because - Answer like charges
repel



The stator consists of electromagnets. - Answer True



Prep the rotor but do not make an exposure, on a routine basis is a cause of tube
damage or failure. - Answer True



The effective focal spot is smaller than the actual focal spot because the face of the
anode is angled. - Answer True



Besides the oil around the tube, mechanical fans assist in dissipating the heat
generated when creating x-rays - Answer True

The high voltage transformer primary side is on the _________ primary circuit

, The timer circuit is on the _________ primary circuit



The step-down transformer is on the _________ filament circuit



The device that regulates the incoming power supplied to the x-ray circuit to maintain
220 V. is called the _________ line compensator



The devices that change alternating to direct current are the - Answer rectifiers



The purpose of the filament circuit is to - Answer boil electrons off the filament
(thermionic emission)

from first to last:



I. kilovoltage is rectified

II. voltage is adjusted at the autotransformer

III. anode and cathode develop large positive and negative charges
