Some electronic circuits require a power supply with positive and negative outputs as well as zero volts 0v.
Power supply circuit symbol.
Constant current source the symbol represents an independent current source which delivers constant current.
Symbol with and indicates dc direct current source and symbol with sin wave indicates ac alternating current source.
The fuse will break the circuit if excessive current flows and saves the other devices from damage.
Usually depends on other sources voltage.
It applies dc supply to the circuit.
These are represents power supply and bias details in circuit diagram.
A single cell is often called a battery but strictly speaking a battery is two or more cells joined together.
Power supply symbols cell.
Crystal and resonators are important to produce clock pulse for microcontrollers and other circuit.
A battery is more than one cell.
Electrical symbols electronic circuit symbols of schematic diagram resistor capacitor inductor relay switch wire ground diode led transistor power.
This is called a dual supply because it is like two ordinary supplies connected together as shown in the diagram.
Dc supply this represents the dc power supply.
Ac supply this represents ac supply in the circuit.
The larger line is positive.
The larger line is positive.
Converts light to electrical energy.
Ac supply circuit symbol.
