Every electronic and electrical appliance in this world runs with power. When this happens, some energy is dissipated in the form of Heat. Whereas the Power is the flow of voltage and current in a […]
In the previous tutorial, we had discussed the applications of current, voltage, and importance of Coulomb’s law in electricity. But, without ohms law the operation of an electric circuit becomes incomplete. To fulfill this, Ohms […]
There are many types of conductor and insulator used in electrical and electronic circuits. Substances covered with metal shields are the electrical conductors. In a conductor, electric current flows in the form of negatively charged […]
Electricity travels through different materials like copper. But have you ever thought how metals conduct electricity? Do all metals conduct electricity and why? In this tutorial, you will know the different types of conductor and […]
Here is the circuit diagram of an independent water pump switch controller with ‘soft’ on/off buttons. Since the circuit uses low-voltage switches, even a kid can operate it safely. Besides, there’s also a dry-run protection […]
As you may know, bathroom is possibly the most dangerous area in your house when it comes to electrical safety because water is a sound electrical conductor. The consequence of an electric shock is far […]
Electronic Magnet Evaluator is a simple device incredibly useful for experimenters and students. With this little gadget one can not only detect the presence of a permanent magnet but also find out its south (S) […]
This circuit is designed in response to a request made by my beautiful neighbor. What she desired was an inexpensive device to record and replay customized voice messages. Now it’s the frontend of her simple […]
Now you can build your own simple security alarm button using a tiny microcontroller chip PIC12F675 ! The circuit is nothing but an aural alert unit, which raises a warning tone when the trigger button […]
