Electrical symbols are used in electronic circuits to represent the circuit components visually. In this sheet, the basic electrical engineering symbols are provided. The list and their details:
Cell: A single cell which acts as a DC Source.
Battery: Combination of two or more than two cells.
AC Voltage: Any source which provides AC source.
AC Current: A current source which provides ac current.
Lamp: Commonly used load for testing.
Capacitor: A charge storage device.
Variable capacitor: Provides a variable capacitance at the output.
SPST: Single Push Single Throw button
SPDT: Single Push Double Throw button
Wires not crossing: Wires that are not connected to each other.
Wires crossing: Wires that are connected to each other at a node.
Fuse: The over-current protection device.
Resistor: A current controlling device.
Variable Resistor: The resistor whose values changes.
Buzzer: A sound device.
Speaker: A sound device.
