Home Made Circuits and Schematics

Conceptual meaning of terms have been introduced and applied to simple circuits. Mathematical relationships The path of a positive test charge leaving the positive terminal of the battery and traversing the external circuit would involve a passage Did you know play dough conducts electricity and can be used to make play dough circuits this recipe from Squishy Circuits. For the conductive dough we used a standard play dough recipe with salt. The next task is to test your doughs, set up If you are a do-it-yourself auto mechanic who understands basic electrical circuits, you can verify the presence or the absence of electrical power in your vehicle quickly and confidently by using a 12-volt circuit tester. Turn on the vehicle's electrical Generally, you can check and test alternator with this procedure 1. Clean the positive and negative battery terminals to ensure a good connection with the tester's clamps. 2. Connect the positive and negative clamps to the appropriate battery terminals. This is done by testing the Left Turn, Right Turn, Tail/Marker, Brake and Back Up circuits on the trailer. The tester indicates approximate amount of current in each circuit. It will also test the voltage of the external battery connected to the trailer Before testing of the charging circuit, the battery is to be checked first and to be assured that it is healthy and in the charged condition. If it is faulty, it has to be replaced with a good battery. The next test is the alternator output test .

Both the Tekonsha Trailer Wiring Circuit Tester # 8010 and the Hopkins Tow Doctor Trailer End Test Unit # HM50928 are for testing the wiring of your trailer. Both will work with incandescent and LED lights. However, the Hopkins will not display amperage I built a simple IR detector using Snap Circuits to test how well the floppy disk would absorb visible so they wouldn’t be useful to charge the rechargeable battery in your solar garden light, but they do produce enough energy to do useful work This site was created by James Chevalier in 2010, and has remained self-funded since then.
