Questions: QUESTION 5 / 10 An exposure is made using 200 milliamperes (mA), and a 300 millisecond (ms) exposure time. Calculate the milliampere-seconds (mAs). 21 mAs 60 mAs 74 mAs 270 mAs Report this question

Solution Steps

We need to calculate the milliampere-seconds (mAs) given the current in milliamperes (mA) and the exposure time in milliseconds (ms).

First, convert the exposure time from milliseconds to seconds: \[ 300 \, \text{ms} = 0.300 \, \text{s} \]

Use the formula: \[ \text{mAs} = \text{mA} \times \text{time (s)} \] Substitute the given values: \[ \text{mAs} = 200 \, \text{mA} \times 0.300 \, \text{s} = 60 \, \text{mAs} \]
