Hi, sorry if this is a dumb question but does anyone know if the analog pins on an Arduino Uno have a resistance and what this value would be. Also if you knew this value and the voltage flowing through the pin could you calculate the current flowing through the circuit. Thanks for your help.

Resistance of Arduino Analog Pins

100meg ohms.

Voltage doesn't flow, current flows.
