Which of the following would produce the greatest film density?

Question

Quizplus · Accepted Answer

Film density is the degree of blackening of the film after exposure and development. The greater the film density, the darker the image appears. Film density is directly proportional to the amount of radiation exposure received by the film. The exposure is the product of the tube current (mA) and exposure time (in seconds).

So, we need to choose the combination that produces the highest exposure. Among the given options, the highest exposure can be achieved with option B - 10 mA X 2.5 seconds = 25 mAs. The product of mA and time is highest in this option, making it the best choice for producing the greatest film density.
