You might have noticed street lights that automatically turn on at night and off during the day. Knowing how relays work, you can create a circuit capable of controlling these types of lights using just a photoresistor, two NPN transistors, and a relay: The circuit uses an LDR (Light Depen...
If the windows work, it may have been a temporarily overload that caused the fuse to blow. Trying to lower a window that is frozen shut in the wintertime can do this and/or break the window mechanism inside the door.If the fuse is okay, there may be a break in the wiring that ...
Because of its simplicity and confirmed reliability, this form of permanent magnet relays or polarized relays are widely used in most RCD or RCCB applications. Swithing Mechanism The switching mechanism of the RCD should be very sensitive as and also should be able to deliver adequate pressure on...

You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram. ...
Once located, check the terminals of the relay for power and ground and then replace the relay to recheck the system. You can swap the relay for a similar one such as the power windows or door locks for testing, many of these relays are the same....
The easiest way to test a relay is to simply swap it out with a known-good part. Relays are often cheap, but having one on hand isn’t always going to happen. Watch out, though—whatever it was that cooked your first relay can do exactly that to your second one if the root of th...
However, no modern computer uses relays -- it uses "chips." What if you want to experiment with Boolean gates and chips? What if you would like to build your own digital devices? It turns out that it is not that difficult. In this article, you will see how you can experiment ...

A control board is a circuit board that consists of several resistors and relays. These components control the speed, temperature, and other functions of your furnace’s fan and burners. In most cases, you can find this control board located inside the control panel of your furnace. The contr...
