This applet teaches how to solve simple resistive circuits the same way a human does ( the same way it is taught in class )
Combine series resistors into one,
Combine parallel resistors into one,
Again and again until you get a 1 resistor circuit with a battery.
Apply Ohm's law,
Replace the equivalent resistors, etc ..
You can choose among 9 circuits (* 9 different resistance/voltage values ) = 81 exercises.
The most complicated:

Any comment ( good or bad ) will be welcomed (It would be easy to add more circuits )
