Power Supply Circuit Symbol

Constant current source the symbol represents an independent current source which delivers constant current.

Power supply circuit symbol.

The larger line is positive. Some electronic circuits require a power supply with positive and negative outputs as well as zero volts 0v. Crystal and resonators are important to produce clock pulse for microcontrollers and other circuit. The fuse will break the circuit if excessive current flows and saves the other devices from damage.

Electrical symbols electronic circuit symbols of schematic diagram resistor capacitor inductor relay switch wire ground diode led transistor power. Usually depends on other sources voltage. These are represents power supply and bias details in circuit diagram. Dc supply this represents the dc power supply.

A single cell is often called a battery but strictly speaking a battery is two or more cells joined together. Controlled current source it is a dependent current source. A battery is more than one cell. This is called a dual supply because it is like two ordinary supplies connected together as shown in the diagram.

Power supply symbols cell. Ac supply this represents ac supply in the circuit. Converts light to electrical energy. The larger line is positive.

It applies dc supply to the circuit. Symbol with and indicates dc direct current source and symbol with sin wave indicates ac alternating current source.
