LMRT CORE 2024 UPDATE COMPREHENSIVE EXAM
PREPERATIONS QUESTIONS AND CORRECT ANSWERS
100% GRADE A+
What is hysteresis loss?
-(Lagging loss) in the core because energy is expanded as the continually changing Ac current
magnetizes, demagnetizes, and remagnetizes the core material .
Which type of generator has voltage that never drops to zero?
-Multiphase Generator
What emerges from the port window and what type of voltage does the cathode receive?
-Useful beam
-Electrons (-)
How can tube life be extended?
-Buttons pressed fully
-Warming up the tube
What are features of the main X-ray circuit
-adjust amperage
-adjusts voltage
-Increase efficiency of x-ray production
What is a component of the secondary side or high voltage side of an x-ray circuit?
-Rectification System
Two Types of electrical charges
-Protons
-electrons
Which device is adjusted when the KVP is selected on the control panel?
-Autotransformer
Frequency and Wavelength have what type of proportional relationship?
-They are inversely proportional
Wave length
Frequency
-is the distance between any two successive points on a wave
-is the number of waves that passes a particular point in a given time frame or number of cycles
per second
How an object can be electrified?
-contact
-friction
