Unformatted text preview: 1/3 of the film and take exposures until all of the factors are completed. Milliamperage X Exposure Time = mAs kVp SID 1. 75mA X 0.010 = 0.8 50 40 2. 150mA X 0.010 = 1.5 50 40 3. 250mA X 0.010 = 2.5 50 40 PROCESS THE RADIOGRAPH. PLACE THE RADIOGRAPH ON A VIEWBOX AND ANSWER THE FOLLOWING QUESTIONS: 1. What happens to the cathode filament as mA increases? 2. What happens to the number of electrons produced when mA is increased? 3. What happens to the number of x-rays produced when mA is increased? 4. How is radiographic density related to milliamperage? 5. Did the mAs change when the mA changed? Why? 6. How is radiographic density related to mAs? 6...
