Electrical week 2

There are a few things I've taken away from electrical so far. There are high resistance voltage drops, opens, and shorts. One of the things that I'm still figuring out is determining whether it's a short to power or a short to ground. It seems that when a short bypasses a switch it is a short to power. If it blows a fuse then it is a short to ground. Another interesting scenario is if there is a HRVD that drops so close to zero it almost looks like an open.
