In each blank, try to type in the
word that is missing. If you've
typed in the correct word, the
blank will turn green.
If your not sure what answer should be entered, press the space bar and the next missing letter will be displayed. When you are all done, you should look back over all your answers and review the ones in red. These ones in red are the ones which you needed help on. Question: line voltage compensator is incorporated into the circuit to:Answer: maintain a constant kVp Question: this meter measures the passing between the electrodes of an x-ray tubeAnswer: millammeter-seconds Question: the voltage in the secondary circuit of a modern x-ray cicuit is how many times greater than in the circuit?Answer: 1000 times Question: the high temps that are needed to produce the thermionic emission in the of an x-ray tube require a current of about:Answer: 4-6 amps (temp of 2200 celcius) Question: why are the majority of the components of the x-ray tube found in the circuit?Answer: reduce the risk from shock Question: type of current passing between the seconday of the high-tension transformer and the Answer: High voltage (kV) Question: large focal spot is used for settings what mA?Answer: 300 Question: higher mA= _______ current, _________ temp of the filamentAnswer: , higher Question: the high tension transformer is located in an oil-filled tank that also houses Answer: rectifiers and filament Question: an increase in kVp will also cause an increase in _____________ that requires the use of a _________________.Answer: cloud, space charge compensator Question: this meter measures Answer: ammeter Question: main component of a line-voltage that is capable of storing small amounts of electrical chargeAnswer: Question: the pre-reading kV meter is incorporated into the x-ray panel to measure the potential difference on theAnswer: side of the high tension transformer Question: most common device used to create the high potential across the x-ray tubeAnswer: high transformer Question: reduction of voltage and development of high amperage by a step down occurs in theAnswer: filament portion of the Question: in a radiographic unit, the milliammeter will only during the activation of theAnswer: second (exposure) stage of the switch Question: circuit? 110, 220, 440 voltsAnswer: primary Question: circuit? 10-12 voltsAnswer: circuit Question: which circuit? 25,000-150,000 Answer: secondary Question: five main components of the high or high voltage circuitAnswer: transformer, the millampere-seconds (mAs) meter, the rectifiers, the high cables and the anode of the x-ray tube Question: why can you only mAs meter readings immediately after an exposure?Answer: tube current is only generated the second phase of the x-ray production process Question: powerAnswer: Question: power Answer: current X = watts Question: a transformer has 200 primary and 20,000 secondary turns of wire. what secondary voltage will be induced if 110 volts are placed on the coil?Answer: 11,000 (11 kVp) |
