What is a circuit diagram and its prerequisites to understand? The answer of this question is that:
A circuit diagram is termed as: “a visual display of an electric circuit using either industry standard symbols or basic images of parts”. It is also called as electronic schematic or electrical diagram. These (Circuit diagrams) are the milestone of each electronic device. These are used for designing, constructing and troubleshooting in an electronic circuitry.
In a circuit diagram; symbol usage is based on the audience viewing / using the diagram.
It has two major types:
- Pictorial Circuit Diagram:
It uses basic images of components. It is designed for less technical audience as it is clear from following diagram that we have a battery as a power supply source, a resister for limiting the current value, a voltmeter for voltage measurement & an ammeter for current measurement.
- Schematic Diagram:
It uses industry standard symbolic representation of components and their interconnections within a circuit. It is designed for a highly technical audience, especially electrical engineers or the personnel involved in troubleshooting activities.
Prerequisites of circuit diagrams:
The main prerequisite of a circuit diagram is the final analysis that which type of audience will be going to view the diagram.
By keeping in view the target audience, there are some basic technical things to be understood for better design, construction and troubleshooting.
Each electric / electronic part has number of unique symbols used in circuit diagrams. So, to develop a circuit diagram; one should be first aware of symbols used for electrical instruments.
Here we have made a comprehensive table containing details of each component / instrument name, its symbol and its meaning in electrical terminology.
Mostly used Electrical Symbols
Hope you must have gotten what is a circuit diagram and its prerequisites to understand.
After being aware of component name and symbol; one should also check its function in real world. You can check functionality from Google. Next most important prerequisite is the selection of efficient software for design and construction of a circuit diagram.
