1.Since it is difficult to draw pictures of real wires, bulbs or transformers on a diagram, any complex circuit is easily represented on paper using these symbols.
2.list of Basic Electrical Symbols Below are the most commonly used symbols in daily life and
basic electronics:
1.POWER SOURCES
2. Switches & wires
3. Loads & Passive Components
4. Measuring Instrument
why are electrical symbols important?
1.Universal Standard: These are based on a single standard (like IEC or IEEE) across the world, so that a circuit diagram made in India can be easily understood by an engineer from any other country.
2.Saves time and space: Wiring diagrams of complex machines or homes can be drawn very small and clearly on paper.
3.Error Prevention: Circuit symbols help in quickly identifying the correct component during fault finding or repair.
