I know that ISO is sensitivity to light. What does the change in ISO technically do to the sensor (or other parts of a camera)? Does the change in ISO change the rate at which electricity is stored and discharged in the capacitors in the sensor (and therefore change the sensitivity of the sensor to light)?

I suggest you this explanation, is very precise, accurate and easily accessible to all levels of knowledge

Thank you very much. That is excellent. Dynamic range and tonal range are interesting and how the voltage is effected by change in ISO.
"However, the sensor's sensitivity doesn't actually increase; the camera is just amplifying the data it produces."
Yes, and that is why modern cameras has, in addition at a better sensor, better amplifying algorithms
I love electronicm physic math computers and what else so i'm glad to be helpful ;D
