Anelectromagnetis a simple device made up of a wire wound in a coil around a core of ferromagnetic material such as iron. This is a very interesting device and it is easy to build one yourself. All you need is an iron nail and some insulated wire. Wind the wire into a coil around t...
When a lot of light hits it, it has almost zero resistance -- it conducts electricity very well. When no light hits it, it has high resistance -- it conducts electricity poorly. In an extremely simple circuit, you would wire a CdS cell directly to a relay (see How Relays Work), so...
Attach the wire to the relay terminal opposite the battery terminal. Route the 16-guage wire up the fenderwell and through the firewall to just below the dash. You will see rubber grommets usually around or just under the brake booster where the throttle cable comes through the firewall. Us...
You can also use them in cascades or for Boolean logic operations to manage complex switching arrangements. A relay is a simple electromechanical switch made up of an electromagnet and a set of contacts. Relays are found hidden in all sorts of devices. In fact, some of the first com...

an intruder might break through a window, so you could make the glass itself a circuit. The easiest way to do this is run a current through a thin line offoil wireaffixed to the surface of the glass. If a burglar breaks the glass, the circuit is broken, and the alarm is triggered....

To show you how to wire the relay, let’s build a temperature controlled relay circuit that will turn off a light bulb when the temperature of a thermistor reaches 150°F.Thermistorsare really useful with 5V relays. You can use them to turn off a large motor if gets too hot or turn ...
The inductor in a boost converter plays the important of stepping up the input voltage. The crucial aspect which becomes responsible for activating the boost voltage from an inductor is due to its inherent property of resisting or opposing a suddenly induced current across it, and due to its re...
