Photovaltic Cells

Pressing the button switches on the two focusing lamps. The solar panel directly converts light energy from the lamp into electricity. A mini fan at the bottom of the tube blows air that keeps the ball floating. The height of the ball depends on the speed of the fan which itself depends on energy recieved from the lamps. Regulate the amount of light from the lamps to see how it affects the output which is the height of the ball. Readings on the ammeter and voltmeter show the amount of current and voltage respectively.
