Hi.
I designed and built this circuit: https://www.circuitlab.com/circuit/ebrb94/avr-master/
When this circuit has no power supplied, between +5V and GND I measure 4860 ohms resistance. When I attach a 9V battery and turn the circuit on, the resistance between +5V and GND is unmeasurably high. Where does that resistance come from when there is no power? I'm measuring with a DMM on a real circuit. I've checked for solder bridges etc.
