Okay, for a beginner who wants to start getting into electronics more for haunting, what is the best tool to get to read how much poser is going through a wire, like to find out how much power is going to a servo or LED or something?

you can get a digital multimeter for 10-15 bucks. I got one from Harbor Freight on sale for like 6.

For most applications a good quality Digital Multimeter (DMM) is what you need. These can run from $6 at Harbor Freight to $100s for the really high-end meters. If you are going to be using it with low voltage stuff and you don't need fast response time or really tight precision, go with a less costly unit. I have one of the $6 HF DMMs and its good for fast continuity checks wall wart outputs, and so on, but I also have a $200 Fluke 175 that I use for AC checks and signal monitoring. You can spend a lot more than that, too. If all you need is simple continuity and low voltage power checks, go cheap, but I'd never use the $6 meter on AC line voltage.

If you mean how much voltage, you can use just about any multimeter but if you want to find out how many amps you are pushing through a line you need a amp probe, you can get a meter that does both for about 40-50 bucks I have a simple T-5 Fluke that does both works great, and like Otaku stated above if you are looking for precision your looking to drop a good amount of money.

Okay, I ordered one, so I hope I can get help figuring out how to use it when I need it?

For now I just need voltage.
