If you’re talking about outlets, switches, ceiling fans or overhead lights, the concept is rather simple. Just remember that electricity flows like water. Hot wires are normally black, but can be other colors, neutrals are almost always white, and ground is usually green (sometimes it’s a bare copper wire.)
Familiarize yourself with the layout. Every outlet box in your home will usually have at least 3 wires in it: A hot, a neutral and a ground. In the case of a switch that controls a ceiling fan or overhead light, for instance, will have a feed (3 wires) and an out (3 more wires going to the fan). The 2 neutrals (white in the US, generally blue elsewhere) will be wire-nutted together, and the 2 grounds (bare or green, sometimes stripped with yellow) will be wire-nutted together. The two remaining hots will attach to the switch itself (the feed hot on the bottom, and the out hot on the top).
For outlets, all the wires will attach to the outlets. A regular two socket outlet will have 5 screws behind it. Two will be for the neutral (white), two will be for the hot (black) and one for the ground (green).
