How to connect a diode?

A standard diode is a light bulb, which serves to indicate the operation of certain devices. In this article, we will consider how to connect a diode, and explain briefly the principle of the operation of diodes.
What you need to build
In order to assemble the working chain, we need the following:
- The diode itself;
- Resistor not less than 25 kilo-ohms;
- Rectifying diode;
- Soldering iron and solder;
- Cord from the electric kettle.
Before you collect all the elements,attention to the length of wires coming from the LED. The long end of the wire is a positive pole, while the negative end always has a short end.
Note that the rectifier LED has a cathode and an anode, respectively, positive and negative outputs. The positive output is light, while the negative output is dark.
At the heart of the principle of LED work liesindication. The current that passes through the light bulb in the LED gives the so-called spectrum. Depending on what spectrum the light bulb has, the light will be presented in a specific color spectrum. As a rule, LEDs come in all colors of the rainbow, although recently one can often meet LEDs of various color combinations. In addition, one LED can work in a different color spectrum.
- First you need to solder the LED to the resistor. Connect the positive end to the resistor, and the negative end to the anode of the rectifier diode.
- Now it remains only to solder the cord wires and connect the cord with a 220-volt outlet. If desired, you can use a fuse in this circuit.
We strongly do not recommend touching the legsLED during its connection to the outlet, since the output voltage will be about 100 volts, which is a potentially dangerous voltage for a person.
