Reddit reviews There Are No Electrons: Electronics for Earthlings

If you want to read a fictionalized electronics course I would recommend There Are No Electrons. I am almost finished with it after a couple days because I can't seem to put it down! Engrossing, entertaining, and educational. You truly won't be sorry.
(Full disclosure: I have nothing to do with this book. It's just amazing and has made electronics an accessible hobby to me, whereas before it just seemed like black magic)

May I suggest the weirdest book ever written on electronics, "There are No Electrons: Electronics for Earthlings"

It's weird, it's wacky, it's also highly educational and it worked for me.

Most of the comments here are viable solutions and are probably the simplest way to explain those powers.
Coming to your character, there are few out there with super powers that make no sense, and this ruins the story arc as their powers aren't properly defined. This ends up with the writer resorting to a deus ex machina when his character is in a bind, and the writer bends the laws of nature to get him out of it.
I suggest you learn a little bit more about electricity. These comments have clearly described how your hero's powers work. But knowing more about the subject will allow you to write better and more creatively.
I know that it can be a hard subject to learn. I suggest reading There are no electrons - Electricity for earthlings by Ken Amdahl. This book is written as a story. You don't need to have any prior knowledge of Electronics or math and this book clearly helps you understand the basics of electricity. You can finish it in a day its pretty small.

Hope this helped. Good luck!

This is a most excellent book...

From the absolute basics (electrons) to the operation principles of radio waves.

You probably need to be more specific... like what you plan to accomplish (robotics, microcontrollers, amatuer radio).

For electronic theory I recommend: There are no electrons: Electronics for earthlings

Read this, trust me you'll love it and everything about simple electricity will finally make sense...

Read Electronics for Earthlings. It's basically like taking an LSD trip and understanding electronics at the end.

All these comments are great, but the absolute beginning is here!

Next read the book suggested by ryzic. If you have the money, id buy the companion kits that Make sells for the book.

After reading those two books and doing all the projects, look into some "project kits." Check out sparkfun, The Evil Genius series of books, or my favorite the Nuts and Volts store.

After three or four "project kits" just find schematics and figure out how to buy all the parts yourself. Really the world is your oyester and with enough struggling you can build anything. Some ideas that always get people excited: a Tesla coil, cell phone jammers, tasers, ultrasonic range finders, a robotic arm, mechanized nerf gun, anything you think is cool and can find a schematic for.

From there you a going to find yourself really interested in microcontrollers. And well.. Thats a different comment lol!

You might consider checking out this book. It teaches the basics in a very nontraditional way.

For a very basic but thoroughly entertaining introduction: There are no Electrons: Electronics for Earthlings.

Also: Teach Yourself Electricity and Electronics.

The voltage will always be the same - 110v or 230v at the wall, 5v on the supply to the MicroUSB end. I think what you mean is that you have a charger capable of producing a high current.

This confused me for the longest time - I found searching for pages like this one ( http://www.kpsec.freeuk.com/voltage.htm ) helped, but the 'There are no Electrons' was the most useful - http://www.amazon.com/There-Are-Electrons-Electronics-Earthlings/dp/0962781592

> Doing projects around the house

This isn't math directly, but if learning electricity is on your to-do list, then I'd recommend There Are No Electrons: Electronics for Earthlings. It uses a bunch of analogies to explain electricity and how common electronic appliances and components work layered over top of a funny story that makes it not so dry and a lot more memorable.

By the end, you should know enough to be able to troubleshoot and fix simple electronics in your house including rewiring sockets/appliances, not because you got some guide specifically for rewiring sockets, but because you can reason about it and how it works.

Check out There Are No Electrons: Electronics for Earthlings by Kenn Amdahl

Its from this book.

Basically, the author, Kenn Amdahl, creates his own analogy where there are Male Greenies (Electrons), and Female Greenies (Protons). Greenies are these tiny little green dudes that live inside electronics. The male greenies are always looking to go party with the female greenies, and the female greenies are always hosting parties with music blasting, beer, and what not. Voltage is the male greenies' need to party, the current is how many are traveling along the roads (wires, etc.), and resistance is obstacles and conditions of the road.

With this Amdahl is able to create an analogy for most of the properties of electricity without it falling apart like the water analogy. He inter-weaves all this with a fictional story of how one of the little greenies is charged with the task of teaching him the "truth" of how electronics work, a wizard who makes Amdahl teach him electronics so he can repair a time machine, and other interesting pieces. It is a great read.
