I am reading up on microcontrollers and I want to know the current that RA0 is drawing when the switch is open but I think I'am getting it wrong. Also my electronics knowledge is elementary at best.
I=V/R I=5V/4700Ohm I=1.06mA (rounded off)
I expected to get something close to 50mA or something because of the table below
I need some help.
