Was wondering if anyone could help me with the equations to calculate power out from a windmill with a resistive load from DMM readings of voltage and amperage. Also how does the load relate to the power output.
For example, if I have a 12VDC 10amp rated motor/generator with a 2VDC 300mA load and I get voltage readings of 3 volts and amperage of 3.5 amps at 6.5 m/s what is the power being produced by the generator?
What is the effect on output is I increase the load to say 7.5V and 900mA?
please help
