How to KNOW if a TRIAC is DAMAGED with this HOMEMADE Tool Easily. In this video tutorial of easy projects of basic electronics we are going to see the TRIAC or triode for alternating current, the difference with the thyristor is that it is unidirectional and the TRIAC is bidirectional, how to Check with this Homemade Tool or homemade invention, we are going to see the difference between the btb16 and the bta16, in this case we are going to build a homemade tool to check all kinds of TRIACs and find out if the electronic component is in good condition or damaged since it is responsible for many breakdowns in many electronic devices or household appliances such as washing machines, dryers , hair dryers, dishwashers and many other devices, for this we are going to use a recycled electrical box from an old electrical installation that is no longer used, a double pole switch, a push button that we can also recycle from microwave ovens that are no longer used. A lamp holder is used, and a 60w filament lamp can also be used as a microwave oven bulb. das or refrigerator, an electrical resistance of 1k of 1w, we can recycle it from some electronic card of electrical electronic devices or household appliances and a power cable also recycled from an old television, and finally a connector to nail the TRIAC those we also recycle from an old television. As tools we are going to use tin, tin iron or soldering iron, some recycled electrical cable from many household appliances and I also leave you the electrical diagram so that you can build it step by step remember that it works with the 230v home network voltage and it is very dangerous. A minimum knowledge of both electricity and electronics is recommended. Let's try btb12, bta16, btb16, if you like the video, don't forget to leave your LIKE, thanks.
