What is the difference between diodes, anodes and cathodes?
The polo diode is an essential part of a large number of electrical systems. These components have two terminals - those that take electricity and one that releases it. This process works in one way; If the terminal takes electricity, it does not leave energy back. The cathode is part of a diode that allows energy flow, and the anode is a part that allows it to flow. It is a combination of these two elements that allows the diode to work.
The physical design of the diode varies slightly on the reason for its use, but certain factors remain the same. The diode has two terminals, a cathode and an anode that are connected by a small amount of semiconductive material. This material is usually silicon, but a wide range of different materials can be used. The whole assembly is surrounded by a glass or plastic covering. LEDs can be of any size, and while most diodes are not too large, they can be almost microscopically small.
The anode takes electricity. This terminal gets its name from a negatively charged anionThe ones that move to it during a normal electrochemical reaction. The charging of the anode varies depending on the function of the device. If the device uses power supply, the charge is negative and if it creates power, its charge is positive. This polarity shift allows the electricity to flow properly from the terminal.
Cathode is essentially the opposite of the anode. The cathode allows energy flow from the device. This terminal acquires the name from the positive charged cathodes, which attracts during the reaction. When the device uses power supply, the cathode is positive and is negative when it generates power.
The material in the middle of the diode is a semiconductor. Semiconductors are materials that do not work electricity as a standard conductor, but do not prevent it as an insulator. These materials fit Dotween and have very specific properties when electricity flows. Most of the mass -produced diodes use a silicon semiconductor, but those from Germania are not unusual.
Since their invention at the end of the 18th century, the basic diodes did not change much. The materials used to improve them and basic design have become much smaller, but that's really all that has changed. Neither the principles to make them nor their design are much different from the original creation.
The biggest innovation with diodes is in alternative versions inspired by the initial invention. There are dozens of different types of diodes that all work a little differently. These different diodes have various other functions beyond the basic form method. They are provided from a tunnel diode that works on a quantum to a light emitting diode (LED) used as a light source in many modern electronics.
