Our Design its a cream windmill Our Experiment REPLACE WITH DESCRIPTION OF YOUR EXPERIMENT Results EDIT WITH YOUR VALUES Reading 1 Current [ 6.3] mA Reading 2 Current [ ] mA Reading 3 Current [ ] mA Reading 4 Current [ ] mA Average Current = [6.3 ] mA Windspeed at fan = [s ] ms-1 Resistance = [100 ] Ohms Power = I * I * R (remember to convert mA to A) 3.97 mW So with a windspeed of [s ] our turbine generates an average current of [6.3 ] mA delivering [3.96 ] (convert W to mW) mW per second so in 10 minutes it could generate [2376 ] 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 [ 30.9 ] seconds of playback time, enough to listen to about [ 0.2] 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...
