There are many types of electronic components, and each has its own unique set of uses. Some common electronic components include resistors, capacitors, diodes, and transistors. Each of these components has a specific function in electronic circuits.
Resistors are one of the most important components of an electronic circuit. They are used to control the flow of electricity, and can be found in everything from computers to cell phones. Resistors come in a variety of sizes and colors, and can be easily identified by their stripes. The width of the stripes corresponds to the resistor’s value, while the spacing between the stripes indicates the tolerance. For example, a standard resistor with brown and black stripes would have a value of 10 ohms, with a tolerance of +/- 5%. In addition to their value, resistors also have a power rating, which indicates how much voltage they can handle. The most common types of resistors are carbon-film, metal-film, and wire-wound.
Capacitors are devices that store electrical energy, and are commonly used in electronic devices such as radios and television sets. They work by using two conducting plates which are separated by an insulating material, known as a dielectric. When a voltage is applied to the plates, electrons are attracted to the plate with the opposite charge. This creates a static electric field between the plates, which stores energy. When the voltage is removed, the electrons remain on the plate with the opposite charge, and the capacitor is said to be “charged”. Capacitors can be found in a variety of shapes and sizes, and are made from a variety of materials. The most common type of capacitor is the electrolytic capacitor, which uses an electrolyte-filled dielectric to store energy.
Diodes are an essential component of many electronic devices, including radios, TVs, and computers. They are used to allow electricity to flow in one direction only, and they are often used to convert alternating current (AC) to direct current (DC). Diodes are made up of two pieces of semiconductor material, typically silicon or germanium, that are connected to each other at one end. The other end of each piece is connected to a wire that leads to the device’s power supply. When the diode is turned on, electrons flow from the negative lead through the semiconductor material to the positive lead. This allows current to flow in one direction only.
Transistors are another essential component of many electronic devices. Unlike diodes, transistors can be turned on and off, which makes them useful for controlling the flow of electricity. They are made up of three pieces of semiconductor material: the base, the collector, and the emitter. When a transistor is turned on, current flows from the base to the collector. When it is turned off, current stops flowing. This makes transistors useful for controlling the flow of electricity.
Transistors come in a variety of shapes and sizes, and are made from a variety of materials. The most common type of transistor is the bipolar junction transistor (BJT), which uses two types of semiconductor material.
These are just a few of the many types of electronic components that can be found in electronic devices. Each component has its own unique set of uses, and it’s important to understand their functions in order to design and build effective electronic circuits by buying electric components online.
