Features 1. Solar power in electric power: Point the solar demonstrator's battery to direct sunlight (or near an incandescent light over 60W). Connected to the voltmeter at both ends, you can see that the solar cell has a voltage output, the light energy is converted into electricity, with one hand to cover the light, you can see the output voltage changes, indicating that the intensity of the light. and ratio of how much electrical energy is converted. 2. Drive the musical probe: the plug of the music sound plug-in and the two ends of the positive and negative poles of the solar cell must be connected, the battery panel aligned with direct sunlight (or near the 60W incandescent light), you can listen to the speakers send nice music. 3. Solar Battery Drive Motor: Connect the plug of the motor connector to the ends of the solar cell and the battery panel in direct sunlight (or near an incandescent light over 60W), you can see how the motor rotates. 4. Durable Construction The Experimental energy conversion kit is made of premium material, which is hard, not easy to deform, sturdy and durable and has a long service life. 5.
