Power Supply Circuit Symbol

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