RTE 1401 CHAPTER 4 QUESTIONS AND
ANSWERS 2026 100% CORRECT
filament circuit - ANSWER>Consists of a rheostat, a step-down transformer, and the filaments inside X-ray tube
Rheostat (mA selector) - ANSWER>Control the flow of electrical current manually by increasing/ decreasing MA
milliampere parameter - ANSWER>Called tube current - reflects the rate of flow of electrons passing through x-rag
tube during an exposure
When the radiographers adjusts milliamperage on the operating console, he or she is adjusting the rheostat -
ANSWER>
Increasing mA = better for flow, less resistance - ANSWER>
Increasing kVp and decreasing mA = less radiation for patient - ANSWER>
Filament - boils, send electrons to Anode — Cathode - ANSWER>
, focal spot - ANSWER>Determining what filament to use (large or small )
Adjusting rheostat you can change the resistance in the filament circuit. After the rheostat adjusts the current then
hit filament by step down transformer - ANSWER>
Step down transformer Decreases voltage & increase current on secondary side - ANSWER>
Step up transformer increase volaticé and decease current - ANSWER>
What is electrostatics?
Answer: The study of stationary electric charges.
What is electrodynamics?
Answer: The study of electric charges in motion.
Is electric current static or dynamic?
Answer: Electric current is always dynamic.
What are conductors?
