A cell or battery is a device that converts chemical energy into electrical energy. The stack has three parts: the electrodes, the electrolyte and container, but constitute a single unit, the battery is formed by a set of series-connected batteries are rechargeable and usually.Continue reading..
In big cities, or even inside our homes, we are all subject to an invisible pollution, that does not smell and we can say that is imperceptible, but can be fatal if the person is exposed for long periods. One is the electro smog, which is the part of the electricity that was generated, but lost upon passing over ...Continue reading..
What do you think of using a direct output led in its variable source, regardless of the output voltage? It is very difficult to find a simple solution to this problem. Maybe a zener solve, or a way to regulate the voltage and current without many components not endear, as to light a single LED should not have much effort. How to connect a ...Continue reading..
Phantom load is a dummy load , a device that is used to simulate an electrical load , usually for testing purposes. There are basically two types of phantom loads, a de RF, the Power and Audio, in this article we show a load circuit for audio. When you want to test an amplifier, can sometimes be ...Continue reading..
A Lampada LED, abbreviation LED, developed at the Massachusetts Institute of Technology operates 230 percent efficiency. That is not a typo it has an efficiency of 230% and will provide 70% Lighting the world 2020.Continue reading..
This is another simple design that leverages an additional feature of a component. In case the sensor used is a 1N4148 diode Transistor BC547B or with the base and collector shorted. Have you ever seen right here on the blog a Circuit Temperature Sensor using 1N4148 diode, and also the temperature sensor LM35, but this is different because of its simplicity. Circuits ...Continue reading..
For those who ride or develops electronic circuits the need for a source of protection system is paramount. In both blow fuses confess that I ended up having to recycle a blown fuse, abomination. But there is a practical and efficient output that is the construction of an electronic fuse. The electronic fuse is a device that plays the fuse ...Continue reading..
The resistance of an object is a measure of its opposition to the passage of electric current. Discovered by Georg Ohm , in 1827, electrical resistance has a similar concept to the friction in mechanical physics. The resistance unit in the International System of Units is the ohm ( AZ ). To measure, in practice, There are several methods, ...Continue reading..
The automakers Audi, BMW, Chrysler, Daimler, Ford, General Motors, Porsche Volkswagen anunciaram not e Electric Vehicle Symposium, they will agree to support a new connector technology for fast charge, this connector is for recharging the batteries of electric vehicles in just 15 a 20 minutes. This marks the first step towards the standardization of electric vehicle market, ...Continue reading..
Often we have to do complex calculations to build a coil, or to discover its inductance. But to ease our life there are many programs that do this, but do not always have time to be installing these programs, so I'm offering some online calculators calculations coils and inductance. From personal experience I want to note that this is just a theoretical basis ...Continue reading..
