Electronic Components Symbols - POLARIZED CAPACITOR

Capacitor is an electronic device, used to store an electric charge, consisting of one or more pairs of conductors separated by an insulator.


Diode is an electronic device which has uni junction in it. The most common function of a diode is to allow an electric current to pass in one direction (called the diode’s forward direction), while blocking current in the opposite direction (the reverse direction).


An inductor, also called a coil or reactor, is a passive two-terminal electrical component that stores electrical energy in a magnetic field when electric current is flowing through it. They are usually made of copper with ferrite material combination.


Transistors are fundamentally three-terminal electronic semiconductor devices. A bi-polar junction transistor (BJT), pins are labelled as base (B), and emitter (E), collector (C). The only difference between an NPN and PNP is the direction of the arrow on the emitter. Unlike diodes, transistors have two junctions.


A transformer is an electrical device that transfers electrical energy between two or more copper coils or circuits, through electromagnetic induction. They are usually made of copper materials. They are mainly classified as STEPUP and STEPDOWN TRANSFORMERS.


An operational amplifier (op-amp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output. These devices are usually available in IC (Integrated Circuit) form.


Opto coupler is an electronic device in which the electrical energy is transferred in the form of light. These devices can be used as protection devices to save the circuitry on the other hand.


A crystal oscillator is a two terminal electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency.


A microprocessor is an electronic component(IC) that is used by a computer to do it’s tasks. It is a central processing unit on a single chip containing millions of very small components including transistors, resistors, and diodes that work together and has no inbuilt memory.


A microcontroller is an electronic device in which all peripherals such as RAM and ROM (MEMORY), PROCESSOR and I/O functions are integrated on a single chip. A single microcontroller can perform many tasks one after the other depending upon its architecture.


A fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit or an electric load.


An electronic switch is an electronic component or a device that can switch an electrical circuit ON and OFF.


A relay is an electrically operated switch.  Relays use an electromagnet to mechanically operate the switch. They can be operated with different voltages to switch other voltages.


A light-emitting diode (LED) is a two-lead semiconductor device. It is one type of p–n junction diode, which emits light when a suitable voltage is applied to its leads usually ANODE and CATHODE.


A Zener diode allows current to flow from its anode to its cathode like a normal semiconductor diode, but it also allows the current to flow in the reverse direction when its “Zener voltage” is reached.


In general any closed path is a circuit. But in electrical terminology, An electronic circuit is composed of individual electronic components such as resistors, capacitorstransistors, diodes and inductors, connected by conductive wires through which electric current can flow.


Battery (electricity) is an energy storage device that consists of electrochemical cells that transform chemical energy into electric energy.


A voltage regulator generates a fixed output voltage that maintains constant output voltage regardless of changes to its input voltage or load conditions.
