There are many tools in electronics which we use every day without ever thinking about how they work. One such tool is the diode – a component that uses electrical current to create a magnetic field and a voltage drop across it. Diodes are incredibly useful for electronic circuits, but you may never have known much about them. In this post, we’ll explore the basics of diodes, as well as their applications in electronics.
What are Diodes?
A diode is an electronic parts that enables current to flow in only one direction. This makes it a valuable tool for solving electrical problems.
How do diodes work?
When you put two diodes in series, the current through each diode is doubled. This means that if you connect an ammeter (a device used to measure current) between the diodes and set it to read 2 amps, then when you connect the third (and final) diode the meter will show 4 amps flowing through it because each of the other two Amps has been doubled by adding the second and third diodes in series. When you have four or more diodes in series, the current through them all is tripled!
Some common uses for diodes include: as voltage regulators to maintain a certain voltage at a certain temperature; as light-emitting diodes (LEDs); as rectifiers to convert AC power into DC power; and as transistors.
Types of Diodes
Diodes are one of the most versatile and useful electronics tools you’ve never heard of. They can be used in a wide range of applications, from powering small electronic devices to controlling large motors. Here are four types of diodes:
- Zener diode: A zener diode is designed to protect electronic components from overcurrents. When current flows through a zener diode, it creates a voltage that increases as the current continues to flow. This prevents damage to the component and ensures proper operation.
- Thyristor: A thyristor is similar to a zener diode, but its main purpose is to control electric currents instead of protecting against overcurrents. Thyristors are typically used in power converters, which allow electric motors to receive multiple alternating currents (AC) at once.
- Transistor: A transistor is an electronic component that can switch electricity between two states (on and off). Transistors play an important role in many modern electronics devices, including computers, phones, and radios.
- LED: An LED is made up of several semiconductor materials that are arranged so that light can pass through them easily. When an electrical current passes through an LED, it causes the material next to the LED to become hot and emit light.
Other Uses of Diodes
Diodes are electronic parts that have a wide range of uses other than in electronics. They can be used to create light, sound, and heat. Some common uses for diodes include:
Lighting: Diodes can be used to create light by passing an electric current through them. This is how neon signs work.
Sound: Diodes can be used to create sound by passing an electric current through them. This is how speakers work.
Heating: Diodes can be used to create heat by passing an electric current through them. This is how some hot plates work.
