| Question | Answer |
| Line Meter | A voltmeter which monitors incoming voltage. |
| Line Voltage Compensator | A variable contact on the primary side of the autotransformer necessary to ensure that the outgoing voltage is accurate, regardless of fluctuations in the incoming line. |
| kVp meter | Measures the voltage output from the autotransformer. Also called a prereading voltmeter. |
| Rheostat | A continuously variable electrical resistor used to regulate current. |
| mA selector | A control, providing several choices in the amount of resistance in the filament circuit. |
| Milliammeter (mA meter) | Measures the current flow in the high-voltage circuit during an exposure. |
| Rectification | To make right. Ensuring that the flow of current is only in the right direction. |
| Self-rectification | Current flows in this circuit only during the portion of the electrical cycle when the anode is positive and the cathode is negative. |
| Three-Phase Current | generates x-rays more efficiently than single-phase current, decreasing exposure times by 40% to 50%. |
| Tube Rating Chart | A guide used to keep routine exposures below the limits of the tube heat capacity. |
| Synchronous timer | A manually set device used for exposure control. |
| Rotor Switch | When this is activated, the rotating anode begins to spin, and heat is applied to the filament to create the space charge. |
| Phototimer | Photomultiplier tubes that are sensitive to light. It terminates the exposure after a specific quantity of light has been detected. |
| Rectifier | The unit that’s purpose is to change the AC into direct current (DC) so that it flows only in one direction. |
| Single-Phase Current | Results in a pulsating beam. In one of these there are 60 electric cycles that produce 120 impulses. |
