LRA 222 Finals Review Questions And 100% Correct AnswersTarget and induction motor form a part of - Anode Answer
Filaments and focusing cup form a part of - Cathode Answer
A motor responsible for rotation of anode has a principle of- Mutual induction Answer
During rotation of anode, the focal spot becomes a - Focal track Answer
Focusing cup is able to hold electrons together because - Like charges repel Answer
Stator is composed of electromagnets. - True Answer
Failure to fire on a regular schedule is associated with tube damage or failure caused by
preparing the rotor. - True
The effective focal spot is smaller than the actual focal spot due to the anode face
angled condition. - True
Besides the oil surrounding the tube, mechanical fans assist in removing the heat
generated during the production of x-rays. - True
The main power switch is on the primary circuit
The primary side of the high-voltage transformer is connected to the primary circuit
, The timer circuit is located on the primary circuit
The step-down transformer is connected to the filament circuit
The line compensator is the device responsible for regulating the incoming power
supplied to the x-ray circuit such that it will maintain 220 V
The devices which convert alternating to direct current are the - Answer rectifiers
The function of the filament circuit is to - Answer boil electrons off the filament
(thermionic emission)
The major function of the step-down transformer is to - Answer increase the amperage
going to the filaments
Put the following events leading to the production of x-rays in sequence from first to last:
