You can learn about basic electronic components from lessons on how to build circuits, engineering classes, or read about them from books. This guide is an overview of the most common parts of electronics and will save you the stress and hassle of digging for this information.
Most Common Parts in Electronics
This part resists the flow of current in an electric circuit. It is a tiny part of many gadgets but is very important because it ensures the correct flow voltages. Every resistor has a power rating and a resistance value shown by the symbol 0 (ohms). This value indicates the amount of power the gadget can handle without burning.
The electronic charge can be temporarily stored in a part of the circuit called the capacitor. There are two major variations of these; electrolytic and ceramic disk. This apparatus resembles a battery but with a low amount of capacitance.
This component looks like a three-toothed comb. The three teeth are the terminals (the base, the collector, and the emitter). The base controls the flow of current through to the collector and then to the emitter which releases it. Its controlling nature makes it the part of turning a current on and off. If you want to know how an amplifier goes on or off this is how.
This part only allows a unidirectional flow of current through its two terminals, an anode, and cathode. Application of positive voltage starts the flow of current through the diode when the cathode has a negative voltage. A reverse of the voltages disrupts the flow of current. It’s used when one wants to change an alternating current (AC) to a direct current. The most popular diodes are the Zener diode and the Light-Emitting Diode (LED). The latter produces light when current flow through.
This is a loop of wire inside a primary coil that can be a magnet orjust air. A current passed through the inductor results in a magnetic field in its surrounding. The magnetic field becomes stronger when the main coil is magnetic. An inductor works in the opposite direction to the capacitor. While it lets a direct current (DC flow through, it resists the alternating current (ACC).
Integrated Circuit (IC)
This is a mini circuit with all the components found in a large electronic circuit except these are in minute sizes. An example of this is a radar system which has other basic elements like diodes and transistor attached to a small piece of silicon. le are the elementary unit in modern gadgets such as cell phones, microcontrollers, USBs, amplifiers, laptops, name it.
This element on a circuit converts a voltage from one level to another. You may want to use a range of voltages as a power source but your circuit limits you to only one, say 6 V. You can use this regulator to convert to hire or lower voltages.
This component functions like an electromechanical switch. It works just like traditional manual switch except that it is controlled by the power. It is what turns on or off the power of a device. If you have a device with a high power you can use the relay to convert the power to a lower power.
Now that you know the most popular electronic components, do you feel like you can build your own circuit?
