Thomas Alva Edison, who developed the electric light, among many other things, once said:
"From his neck down a man is worth a couple of dollars a day, from his neck up he is worth anything that his brain can produce."
This short app aims to help that part of you "from the neck up".

The complete app covers basic electricity before delving into electronics. Aimed at the total beginner, it is written in a friendly, almost chatty manner trying to impart fun into your learning.
In electronics we look at some simple components, then learn about circuits and how to draw circuit-diagrams. We use a multimeter to investigate voltages in a real, but simple, circuit.

More about Voltage and Resistance
Then we make the circuit a little bit more complicated, measuring voltage-drops across two components, before looking at the variable-resistor. We finish by combining several resistors in-Series to make different values.
We have included some interactive circuit-simulators in which you try-out some ideas before twisting bits of wire together.
