In: Technology

Answer 1

Its volts or lack of that makes up information, live for on dead for off, so a 1 is on and zero is off, thats basically how zeroes and ones are held in a computer.

If variable charge was used it could be mis interpreted what value was being used because electricity is not always 100% reliable to charge up to a point and not further.

There is a very good and easy to understand video relating to this
