In an mAs setting, what does the 's' component represent?

Explanation:
The main idea is that the amount of X-ray exposure is determined by how much current flows and for how long. In mAs, the “s” stands for seconds, the duration of the exposure. The tube current (mA) sets how many electrons are emitted each second, and multiplying by the exposure time (in seconds) gives milliampere-seconds, the total charge flowing and thus the total number of X-ray photons produced. So the s component is all about exposure time, not the voltage (which affects energy/quality) or geometry like focal length.
