ELECTRONIC SYMBOLS

Connector of Electric Current

• Fuse

• Wire

• Joined Wire

• Unjoined wire

Wires are not connected. This can only be shown by bridging wires or by drawing them without blobs

• Wire

• Unjoined wire

• Joined wire

Connected Crossing. This is represented by drawing "blobs" on the point where they are shortened

• Joined Wires

• Unjoined Wires

• Wire

Generates constant voltage. The smaller terminal is negative while the bigger terminal is positive

• DC supply

• AC supply

• Battery

• Cell

Abbreviated as "B"

• DC Supply

• AC supply

• Battery

• Cell

Used as DC power supply. The current will always flow in one direction

• DC supply

• Ac Supply

• Battery

• Cell

Used in circuits where a

probability of excessive current flows.

The fuse will break the circuit if excessive current flows and saves the other devices from damage.

• Transformer

• Fuse

• Cell

• Battery

Used as an ac power supply. Comprises of the primary and secondary coils, that are connected by an iron core. There is no physical connection between the two coils.

Abbreviated as 'T'.

• Transformer

• Cell

• Battery

• Fuse

Used for zero potential reference and electrical shock protection

• Common Ground

• Earth ground

• Chassis Ground

Connected to the Chassis of the circuit

• Common ground
