Power supply circuit symbol.

A battery is more than one cell. Symbol with and indicates dc direct current source and symbol with sin wave indicates ac alternating current source. Some electronic circuits require a power supply with positive and negative outputs as well as zero volts 0v. Usually depends on other sources voltage.

Converts light to electrical energy. The larger line is positive. 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.

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. Used in circuits where a probability of excessive current flows. This is called a dual supply because it is like two ordinary supplies connected together as shown in the diagram.

These are represents power supply and bias details in circuit diagram. Constant current source the symbol represents an independent current source which delivers constant current. Power supply symbols cell. The larger line is positive.

Ac supply this represents ac supply in the circuit. Ac supply circuit symbol.
