Common Electrical Components And Their Uses Include

Resistors: limit the flow of current, used to regulate current, divide voltage, and protect components from overcurrent damage.
Capacitors: store and release electrical energy, used in filtering, coupling, decoupling and delay circuits, and smooth power supply output.
Diodes: can only conduct electricity in one direction, used for rectifying current, stabilizing voltage, signal demodulation, and protecting circuits.
Transistors: a semiconductor device used for signal amplification, switching circuits, and analog signal processing.
Integrated circuits: integrate multiple electronic components on the same chip, used in microprocessors, operational amplifiers, clock circuits, etc.
Relays: control large currents through small currents, used in automation control, switching circuits, and power management.
Photocouplers: convert electrical signals into optical signals for isolation, used for signal isolation, interference prevention, and circuit protection.
