Default Boy Scout Electric Weekend

I 've come up with the idea for an electricity Merit badge weekend. I will be a district camporee. Each troop will have to design, build and test a power generator. 12 volts DC, water, wind or solar powered. They will have to be assembled at the camp and tested before lunch. For wind, I will provide a 36 inch fan. For water I will provide a water manifold off a garden hose necked down to 3/8. Solar....... I could use an education.
The idea I had is a ceiling fan dimmer going to a 12 volt van and an amp meter and a volt meter. as I increase the resistance on the dimmer the load and the amps should go up and the voltage should drop. When the voltage hits 12 volts, that will be the amps I record.
I'm no electrical engineer or electrician. Do I have the right Idea or is there another CHEAP way I can test/judge these things.
Prizes for the most amps and most original.

After the testing the Scouts will be able to go to different stations to wire circuits, replace breakers, and preform first aid on a resuscitation dummy that got himself electrocuted. If anyone touches the dummy before killing the power, they have to laydown beside the dummy until someone else rescues them both. After killing the power the boys will have to call for help and start CPR.

All ideas and comments are welcome and drawings would be a big help. Thanks!!!

You could also touch on Olm's Law. I took basic class at a community college once and three quarters of the semester was dedicated to understanding it.

It sounds like you have some good ideas for your merit badge weekend. As far as ceiling fan dimmers go, they are typically a TRIAC circuit due to the fact that they are AC powered. They do have a potentiometer as part of the circuit but you would need to remove it from the dimmer circuit to use it with 12VDC.

I think I have it figured out. I can get a dozen halogen headlights at the local bone yard. at 8-12 amp draw each. Put each on a switch. Run the Positive through the amp meter then to the switches. the more lights the more amp load. When the voltage drops to or below 12.0 volts. that is where we stop and record the amperage and determine a winner. Cheap and simple.
