When the transistor switches off, the magnetic field produced by the coil collapses, inducing a voltage spike. The flywheel diode provides a path for this spike, protecting the transistor from damage. If you want to learn more about how the transistor works and how to calculate the base resist...
We know that most of the high end industrial application devices have relays for their effective working. Relays are simple switches which are operated both electrically and mechanically. Relays consist of an electromagnet and also a set of contacts. The switching mechanism is carried out with the ...
The meaning of RELAY is a supply (as of horses) arranged beforehand for successive relief. How to use relay in a sentence.
Solid State Relay The above circuit consists of photovoltaic unit with LED which switches on theMOSFETs (Metal Oxide Semiconductor Field Effect Transistors)with 20mA through the LED. The photovoltaic consists of 25 silicon diodes which generates 0.6V output such that making a total of 15V which is...
So buckle up, because your good friends atThe Driveare going to teach you how to test these tiny electronic switches Rob Stumpf Safety First Working on your car can be dangerous. There are fans, belts, and plenty of things that can zap or cut you. Always take proper precautions when wor...

nounElectronicsA device that responds to a small current or voltage change by activating switches or other devices in an electric circuit. nounA crew of workers who relieve another crew; a shift. nounA fresh team, as of horses or dogs, to relieve weary animals in a hunt, task, or journey...
Relays are electrically operated switches that open and close the circuits by receiving electrical signals from outside sources. Some people may associate “relay” with a racing competition where members of the team take turns passing batons to complete the race. ...
If inverters pique your interest,it might benefit you to know how they work. Continue reading Smart switches are fun, letting you control lights and appliances in your home over the web or even by voice if you’re so inclined. However, they can make day-to-day living more frustrating if...
Frame relay uses temporary virtual circuits to send packets over the network through frame relay switches instead of sending them directly over the network's physical interfaces. ISPs guarantee a certain level of bandwidth for a virtual circuit working under normal conditions. The rate is called the...
