Question

It is best to use a large valued resistor as a pull-up or pull down. True or False

Answer 1

True

Step-by-step explanation:

The reason is so you don't pull too much current through it, which simply wastes power. Something like a 10 million ohm resistor will pass enough current to keep the voltage of, say, an IC pin (which is where they're usually used) at ground or at the supply voltage, but it won't pass so much current that a lot of power is wasted.
