Wait a minute! Resistors are supposed to resist current. What the heck does a zero-ohm resistor do? Well, the short story (tee-hee!) is that it’s like a jumper for single-sided surface-mount boards.

Too much and things probably won't work right and also might short out and create a fire risk. Resistor values are measured in Ohms, which indicates electrical resistance. A brand new, still-in ...
