What new exposure time setting would produce the same total milliampere-seconds (mAs) if the mA is changed to 600?

To determine the correct exposure time setting that would yield the same total milliampere-seconds (mAs) when the milliamperes (mA) are changed to 600, you must understand the relationship between mA, exposure time (seconds), and mAs. The formula for mAs is:

mAs = mA × exposure time (seconds).

So, if the mA is increased to 600, you need to find the exposure time that, when multiplied by 600, equals the desired mAs that corresponds to the current settings.

Assuming the previous mA and exposure time produced a certain mAs value, you would need to find the specific exposure time at the new mA (600) that keeps the mAs constant.

If the correct answer is derived from earlier calculations or knowledge of what total mAs was before changing the mA to 600, then to find the new exposure time, you would calculate:

exposure time = mAs / mA.

For instance, if the original mAs was, let's say, 3.0 (this figure is hypothetical but illustrates the concept), you would calculate:

exposure time = 3.0 mAs / 600 mA, which simplifies
