i’m mostly curious about what exactly happens inside of your finger when you touch the touch screen on your phone, does electricity enter your finger or does the electricity in your finger enter your phone?
In: Technology
Electricity in your finger moves in response to the electricity in the phone. The electricity in the phone moves in response to the electricity in your finger moving in response to the electricity in the phone.
Whether this counts as “electricity moving between the two” is really just semantics. This is just a basic capacitor, and while some people may say that “electricity flows through the capacitor” no electrons are crossing that gap. The influence of the involved electrons, however, does cross the gap.
