solar panel specifications
Asked about the electric current is preparing for a DC motor?
I have a small DC motor that took me out of a sharpner automatic pencil, no marks on him. I know that two AA batteries (1.5 V each) connected in series to be humming, which amounts to total 3V. I want to use solar panels to power the engine. I need to know how much power is being absorbed by the motor and solar panels have specifications for voltage and mA in them. How do I calculate the current drawn by this motor?
1. Go to buy a digital multimeter from RadioShack dollars about $ 25. 2. Connect the wires test on river right along the middle and matching color (black and red). Turn the dial to adjust Amp. You may have to set the range of measure "MA" (thousandths an amplifier) 3. Connect the battery to the engine so that the series of lights and spinning. 4. Take a read through the positive and negative terminals of the engine (when running). You can also do anywhere else in the series. His measure should say something like "123 mA", for example. Just make sure that the engine is under the physical power as when the solar panel (s).
