About this video
In this video i show you electrical symbols with name
Electrical symbols are standardized graphical representations used in electrical diagrams, such as circui
it diagrams and schematics, to visually depict electrical components and their functions. These symbols help engineers, electricians, and technicians easily understand, design, and troubleshoot electrical systems. Below are descriptions of some common electrical symbols:
1. Power Source
Battery: A pair of parallel lines with the longer line representing the positive terminal and the shorter one the negative terminal.
AC Source: A sine wave symbol or two alternating arcs representing an alternating current source.
2. Resistor:
A zigzag line or a rectangle symbol representing a component that resists the flow of electrical current, typically used to control voltage and current.
3. Capacitor:
Two parallel lines with a small gap in between, representing a component that stores electrical energy as an electric field. There are symbols for both polarized and non-polarized capacitors.
4. Inductor:
A series of loops or coils, representing a component that stores energy in a magnetic field when current flows through it.
5. Ground:
A downward triangle with horizontal lines beneath it, indicating a connection to the earth or a ground reference.
6. Switch:
A simple line with a break in the middle, representing a device used to open or close a circuit.
7. Diode:
A triangle pointing to a line, representing a component that allows current to flow in one direction only.
8. Light Bulb:
A circle with a filament or a symbol resembling a light bulb, indicating a lighting element in a circuit.
9. Transformer:
Two coils of wire (often drawn as parallel lines) with a common core, symbolizing a device that changes the voltage in an AC circuit.
10. Transistor:
A circle with three lines extending from it, representing a semiconductor device used to amplify or switch electronic signals.
11. Fuse:
A rectangle or line with a circle, representing a device that protects a circuit by breaking the connection if the current is too high.
12. Motor:
A circle with a letter "M" or a symbol of rotating blades, indicating a mechanical component powered by electricity to convert electrical energy into mechanical motion.
13. Relay:
A rectangle with a coil and two or more contacts, representing an electrically operated switch used to control circuits.
These symbols provide a universal way of representing electrical components, ensuring clear communication in electrical drawings.
