Our Experiment
on my first try it didnt work but then i changed the angles and then it worked.

Results
EDIT WITH YOUR VALUES
Reading 1 Current [ 10.1] mA
Reading 2 Current [9.1 ] mA
Reading 3 Current [ ] mA
Reading 4 Current [ ] mA
Average Current = [9.6 ] mA
Windspeed at fan = [6.0] ms-1
Resistance = [100 ] Ohms
Power = I * I * R (remember to convert mA to A)

So with a windspeed of [s ] our turbine generates an average current of [I ] mA delivering [9.2 ] (convert W to mW) mW per second so in 10 minutes it could generate [5520] mW.

If playing music on an iPod classic consumes about 77mW per second, 10 minutes of turbine time (assuming 100% energy transfer efficiency) can power [ ? ] seconds of playback time, enough to listen to about [ ? ] 3 minute songs.

Thoughts
REPLACE THIS WITH YOUR THOUGHTS: HOW COULD YOUR WINDMILL BE IMPROVED, HOW COULD THE EXPERIMENT BE IMPROVED, IS 100% EFFICIENCY ENERGY TRANSFER REALISTIC, WHAT WOULD YOU ASK AN EXPERT, HOW CAN TECHNOLOGY SUPPORT SCIENCE TEACHING AND LEARNING, ETC...
