Solar Charger 5mA

Project Number: 7

Description: Modify the preceding circuit to match this one. Set the meter (M6) to the 0.5mA setting. Place the solar cell in sunlight or near an incandescent light bulb. The solar cell is charging the battery and the meter is measuring the current. This circuit uses a resistor in the pivot stand to change the 0.5mA scale on the meter to a 5mA scale, so read the current on the 0-5 scale. Changing current is usually in this range. Place your hand above the solar cell to see how easily the current changes, and try different light sources.
