Symbol Description Image
Resistor (R) Represents a resistor used to limit current flow.
Capacitor (C) Denotes a capacitor used to store electrical energy.
Inductor (L) Represents an inductor, which stores energy in a magnetic field.
Battery (DC Voltage Source) Symbolizes a direct current (DC) voltage source, typically a battery.
Ground Indicates an electrical connection to the earth or ground.
Switch SPST: Denotes a single-pole, single-throw switch that can open or close a circuit.
SPDT: Denotes a single-pole, double-throw switch that can open or close a circuit.
Fuse Represents a fuse, a safety device that interrupts excessive current flow.

Relay Symbolizes an electromagnetic relay used for switching high currents.
Diode Represents a diode, allowing current to flow in one direction.
Transistor (NPN) Denotes an NPN transistor used for amplification and switching.
Transistor (PNP) Represents a PNP transistor, another type of bipolar transistor.
