The key difference is that you'll use a different setting on your multimeter. Turn the dial to the lowest AC resistance ...

It's a must-have for any toolbox—but there's a learning curve involved. Learn how to use a multimeter for all of your electrical testing needs.

To measure electrical energy, a multimeter has two wire leads. Touch them to exposed wires, and they'll give you measurements. Its dial or buttons determine what type of energy you are measuring ...

If you know the capacitance per foot of wire, then you can calculate how far it is to the open circuit. To determine the capacitance per foot, take a trip to the hardware store, use a known length of ...
