I'm only 16, but I've been around the electical trade for almost all my life, that and this forum have given me a decent basic understanding of how electricity works

however my friend, who is also 16 has just begun working in the trade, working for a fairly large contractor, and like usual he is told "run this wire here, hook these wires to these wires" etc. and he wants to know how it works in a very basic sense, could anyone here give him a basic description? Maybe some tips for begginers? I'll direct him to this thread, Thanks in advance
