**RAD 112 Chapter 4 Quiz - The X-ray Circuit** [RAD 0724\_RAD 112 Radiation Physics and Radiobiology I](https://lms.stellarcollege.edu/course/view.php?id=1811#section-5) Top of Form Question **1** Rectifiers function to AC to DC Question **2** The line compensator is typically wired to the autotransformer The line compensator is typically wired to the autotransformer. Question **3** Place the following events leading to the production of x-rays in order, from first to last\ \ I. alternating current is converted to direct current\ II. voltage is adjusted at the autotransformer\ III. kilovoltage leaves the step-up transformer\ IV. voltage goes to primary side of step-up transformer II, IV, III, I Leaving the autotransformer, the selected voltage goes through the primary and secondary sides of the step-up transformer and is then rectified. Question **4** Ohm\'s law can be written as volts = current x resistance Ohm\'s law is V = IR or volts = amps × ohms. Question **5** *Ripple *refers to the fluctuation in voltage in the electricity *Ripple *is the fluctuation of voltage in the electrical signal. Question **6** With mutual induction, to induce current in the secondary coil, there must be Alternating current flowing in the primary coil of wire Mutual induction requires alternating current to be flowing in the primary coil of wire. Question **7** The rheostat is a variable resistor that\ All of the above Question **8** In a parallel circuit the circuit elements are wired along a single conductor. \'False\'. Question **9** Both AC and DC is used in x-ray production. True\'. Question **10** In the US the electricity that flows through homes alternates at 60 cycles per second Question **11** The step-up and step-down transformer operate on the principle of Mutual induction Question **12** The less the ripple the more consistent the energy of the x-rays produced As the amount of ripple decreases, a smaller range of voltages will be used to produce the x-rays, resulting in the energy of the x-rays being more consistent. Question **13** Within the x-ray tube electrons must always flow from\ Cathode to Anode Question **14** What is the total current flowing through the series circuit pictured below? 3 A Question **15** The purpose of grounding is to neutralize a charged object Grounding is a protective measure that neutralizes charged objects. Question **16** What is the function of the mA meter and where is it located in the x-ray circuit?\ Monitors x-ray tube current; located in the secondary circuit Question **17** What is the output voltage in the secondary side of the step-up transformer pictured below?  800 V Question **18** Voltage and Current have what type of relationship? Inverse relationship Question **19** The autotransformer operates on the principle of \ Self-Induction Question **20** What is the current at A1 in the parallel circuit pictured below? 0.75 A Bottom of Form
