A non-inverting amplifier is perhaps one of the three most elementary circuits of analog electronics, along with circuits of an inverting amplifier and a voltage follower. It is even simpler than an inverting amplifier, since the circuit does not need two

A dimmer is a small-sized device designed to smoothly adjust the brightness of the glow of one or more lamps. Most often, it is a control knob, by rotating which we can change the level of illumination. Name adjustment process

Which have no less than three conclusions. In certain situations, they are able to amplify power, generate oscillations, or transform a signal. There are a lot of very different designs of these devices, and among them - a pnp transistor.

A person far from electricity is unlikely to exhaustively answer the question - what is a dimmer? But many had to deal with the operation of this electrical device. Now we will try to explain in more detail what it is and why it is needed. D

We make a LED lamp for seedlings At the moment, serious companies are not yet engaged in lamps for seedlings. It is unprofitable for them because of the small demand and high cost of LEDs. Therefore, such products are produced in a semi-handicraft fashion in small

The old man took ten brand new lamps, shining like gold, and went around the city, shouting: “Who wants to exchange old lamps for new ones? Who has old copper lamps? Change for new! “Aladdin's Magic Lamp” (Arabic tale). To begin with, the replacement of llamas

The movement of electrons in a wire is first one way and then the other called one oscillation of an alternating current. The first oscillation is followed by the second, then the third, and so on. With current fluctuations in the wire around it, the corresponding oscillation occurs.

Many metering devices that are currently in Russian homes are equal in age to this property itself. A few years ago, the question arose about the need to update this equipment. The situation has become more complicated in connection with the transition of housing stock to h

Presentation on the topic: Current measuring devices Find spiders with ammeters To analyze energy consumption with ammeters, you must first measure all devices working around the clock, such as a refrigerator or frost

  This is a fairly simple diagram of a transformerless power supply. The device is made on accessible elements and does not need preliminary adjustment. As a diode rectifier, a ready-made bridge of the KTs405V (G) series is used, you can also use any
