Question

If 300 mA has been selected for a particular exposure, what exposure time would be required to produce 60 mAs?

1/5 seconds

Answer 1

To achieve 60 mAs with a current of 300 mA, you need an exposure time of 0.2 seconds.

Step-by-step explanation:

If 300 mA has been selected for a particular exposure, and you need to produce 60 mAs, you will need to calculate the exposure time required based on the formula for milliampere-seconds (mAs), which is the product of the current (in milliamperes) and the time (in seconds). Given that mAs = mA × time, to find the time, you rearrange the formula to time = mAs / mA. Substituting the given values into this formula, you get time = 60 mAs / 300 mA = 0.2 seconds.
