|
mAs

Explanation:
Detailed explanation-1: -mAs Formula To calculate milliampere seconds (mAs), multiply the Milli-amps by the time in seconds.
Detailed explanation-2: -The product of milliamperage and exposure time has a direct proportional relationship with the quantity of x-rays produced. Because the milliamperage/second (mAs) controls the number of electrons boiled off of the filament and available to produce x-rays, it is considered the primary factor controlling quantity.
