The formula to calculate milliampere-seconds (mAs) is:
\[ mAs = mA \times t \]
Where:
mAs is a unit of measure that is equal to one milliamp times one second. This unit of measure is most often used in the study of radiology to depict how much radiation is produced over a set amount of time.
Let's assume the following values:
Using the formula to calculate milliampere-seconds (mAs):
\[ mAs = 200 \times 0.5 = 100 \text{ mAs} \]
The milliampere-seconds (mAs) is 100 mAs.
