Windmill

Project Number: 8

Description: Assemble the pivot, mount the wind fan on the motor (M4), mount the motor on the pivot, place the pivot on the base grid and connect it to the meter (M6) using the red & black jumper wires. Set the meter to the 5V setting. Blow on the fan or place it in a strong wind (either outside or near an electric fan). You may need to give the fan a push to get it started. The meter measures how much voltage your "windmill" produces. Adjust the pivot position to see how the voltage produced changes with the angle to the wind.

Snappy: The windmill uses magnetism to change the mechanical energy of the spinning shaft into electricity. The voltage it produces is usually lower than the solar cell, but the current is higher.
