Hi,
I'm working on the basic logic gate troubleshooting worksheet, and I'm just having some trouble understanding the pull-down resistors in questions 18-21. I understand how they work regularly, but I'm not understanding what happens when they have an open. Correct me if I'm wrong, but usually with opens you'll get the voltage across that open but not the current, so I'm just not sure whether or not in these cases whether or not the logic would be a 1 or a 0 going towards the logic gates. So yeah, I'm just a little bit confused.
