Day 4
1. Make sure your windmill works - proof of light
2. Measure its output with a multimeter (voltage, current, power estimates in watts)
4. A wire's thickness is given by its "gauge". Complete a worksheet that describes what "gauge" means and how it is calculated (for "above and beyond" points).
If you are absent, Be prepared to perform these measurements on a windmill the day your return (you won't need to build your own). Once you have your measurements, complete the lab report.
1. Make sure your windmill works - proof of light
2. Measure its output with a multimeter (voltage, current, power estimates in watts)
- Place the wind turbine 2 feet from a large fan running at full power.
- Measure the AC voltage and current (amps) both with and without a load (a light bulb).
- During each measurement, count the turbine's RPM.
- Estimate the peak power by multiplying the voltage and the current.
