Power Supply Circuit Symbol

Converts light to electrical energy.

Power supply circuit symbol.

Ac supply this represents ac supply in the circuit. Usually depends on other sources voltage. Used as ac power supply that is the current will keep alternating directions. The fuse will break the circuit if excessive current flows and saves the other devices from damage.

Crystal and resonators are important to produce clock pulse for microcontrollers and other circuit. This is called a dual supply because it is like two ordinary supplies connected together as shown in the diagram. Symbol with and indicates dc direct current source and symbol with sin wave indicates ac alternating current source. A single cell is often called a battery but strictly speaking a battery is two or more cells joined together.

Electrical symbols electronic circuit symbols of schematic diagram resistor capacitor inductor relay switch wire ground diode led transistor power. It applies dc supply to the circuit. Constant current source the symbol represents an independent current source which delivers constant current. The larger line is positive.

Some electronic circuits require a power supply with positive and negative outputs as well as zero volts 0v. A battery is more than one cell. Dc supply this represents the dc power supply. Used in circuits where a probability of excessive current flows.

The larger line is positive. These are represents power supply and bias details in circuit diagram.
