Final answer:
The current in milliamperes (mA) is calculated by dividing the milliampere-seconds (mAs) by the time in seconds, resulting in a value of 1600 mA.
Step-by-step explanation:
If the mAs (milliampere-seconds) is 80 and the time is 0.05 seconds, to find the current in milliamperes (mA), we use the formula that defines mAs:
mAs = mA × seconds,
which can be rearranged to solve for mA:
mA = mAs / seconds.
Plugging in the given values:
mA = 80 mAs / 0.05 seconds,
mA = 1600 mA.
So the current in milliamperes is 1600 mA.
