The next question of course would be how exactly does the Cadmium sulfide combination lose practically all its resistance when it is dark. For this I have a guess. Post back if you want my guess. It based on the electron configuration that is probably present in the Cadmium Sulfide combination. Anyways do this experiment. Take your solar yard light during the day and put your finger over different components in the circuitry. If the diode(light) comes on, you have found your photo resistor. Oh yes. Do this late afternoon so you know the solar panel has already fully charged the battery. I will try and find a picture of what one should look like. I have found them in my broken solar yard lights. My daughter and I have broken the stems on some of them so they just lay around so we decided to open them up. An LED is a light emitting diode. I just wrote diode above. But the bottom line is that they require a very small current and put out a lot of light, that is why they are so wonderful. Last edited by pgardn : 08-15-2006 at 09:51 PM. |
