Electronic components have?

The following components is the most common components in electronic equipment:
Micro controller
transformer
The battery
The fuse
relay
switch
The motor
The circuit breaker

What's with electronic components?

A microcomputer is used to control a variety of devices small computer, such as electric tools, remote control, medical equipment and office machines. Cells convert chemical energy into electricity. Two different batteries battery are the anode (+) and cathode (-).

Due to excessive current overload fuse helps prevent components. To fuse by connecting, stents, contact and fuse metal materials (such as zinc or copper). As a protection device, circuit breaker can be controlled by remote switch. It aims to protect the circuit from the influence of overload or short circuit.

Switch interrupt current. Four types of switch are respectively: single-pole single-throw (SPST), single pole double throw (SPDT), double single throw (DPST) and the double pole double throw (DPDT).

The relay is closed or shut off the power of mechanical and electrical switch. Relay including the electromagnet, the armature, a series of electrical contacts and spring.

Motor convert electrical energy into mechanical energy. Key components including the rotor, stator and bearings, guide box, shell and rings bolt. From watches, to home entertainment equipment, and vehicles; Motor can power supply for a variety of devices.

What are the active and passive components in the electronic products? Active element including the transistor, and passive components including transformers, inductors, resistors, capacitors. Transformer is often used to step-up or step-down power supply. Resistor to limit current. It is used for thermistor and potentiometer. Similar to low capacity battery, capacitor allow delays in the circuit. Inductance is used to control the frequency.
