LMRT core prep 2026/2027 | Actual Questions and Answers
Latest Updated 2026/2027 (Graded A+)
•
Units for-
Force
Power
Energy
Current
Electrical Charge
Capacitance
i. - ✔✔Newton
ii. Joule
iii. Watt
iv. ampere (amps)
v. Volts
vi. Farads
•
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?
i. - ✔✔-Useful beam
ii. -Electrons (-)
•
How can tube life be extended?
i. - ✔✔-Buttons pressed fully
ii. -Warming up the tube
•
What are features of the main X-ray circuit
i. - ✔✔-adjust amperage -adjusts voltage
ii. -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
i. - ✔✔-Protons
ii. -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
