There are two divisions to the main x ray circuit‚ those are the primary side and the secondary side and I will talk about both of those throughout this paper. Control Console The Control Console is the section of the imaging system that most Technologists are familiar with. It is the Primary side of the main circuit and it includes the incoming current‚ the exposure switch‚ the autotransformer

ballet dancers you think of grace and beauty. While you watch a dancer dance you never think of the physics and mathematics behind their every move. Physics is described as a thing that is all about measurement‚ and that if you know the units of measurement that physics uses and how they work you will understand everything else you’ll learn about (Dennis and Moring 1). The textbook definition of physics is “the study of matter and energy and their relationships” (Zitzewitz 1). Ballet cannot be defined

PHYSICS II ELECTRICITY‚ MAGNETISM‚ SOUND‚ AND LIGHT SERIES CIRCUIT In this unit you’ll begin learning how to analyze circuits. Circuit analysis means looking at a schematic diagram for a circuit and computing the voltage‚ current‚ or power for any component in that circuit. Closely related to the task of circuit analysis is the task of troubleshooting‚ which means figuring out what is wrong in a circuit that is not working correctly. Analyzing and troubleshooting go hand in hand; when a circuit
