Common Electrical Symbols

Resistor: Limits or resists the flow of electric current.

Diode: Allows current to flow in one direction only.

Capacitor: Stores electrical energy in an electric field.

Variable Resistor (Potentiometer)：A resistor whose resistance can be manually changed

DC Supply Voltage (Battery)：Provides a direct current (DC) voltage source.

AC Supply Voltage： alternating current power generation/distribution.

LED (Light Emitting Diode)：A diode that emits light when current flows through it.

Inductor：Stores energy in a magnetic field when current flows through it.

Ground： A common reference point in an electrical circuit, often connected to the earth for safety and stability.
