The electronic components are part of electronic circuits and are used or manufactured in the field of electronics, which is the study of electrical appliances used for control of electrically charged particles, or the flow of electrons to run any electrical operation. Some of the electronics most common are:

Resistance: resistance resists electrical current, and resistance is measured in ohms. Colors in the body of the resistance is a code for the value. The different colors represent the numbers 0 through 9. In a variable resistance, resistance can be varied by moving a knob or slider. A variable resistor is used for the volume control on many devices.

Capacitor: This is measured in farads. A capacitor is used to store electrical charges can be released on demand. Capacitors can be of different types of hard ceramic electrolyte and are two of them.

Diode: A semiconductor device, diodes allow current to flow in only one direction.

Small, cheap and durable, light emitting diodes (LEDs) are special diodes that give birth and allow current to flow in one direction.

NPN bipolar transistor: Used for current control, the currents that can amplify a small amount of dissipation heat and very little debris.

PNP bipolar transistor: Its functions are the same as NPN, but the construction is slightly

different.

Crystal: When a voltage is applied, the crystals can vibrate a specific frequency accuracy.

Integrated circuit having circuits etched therein, a circuit Integrated is a semiconductor wafer can contain capacitors, resistors, transistors, etc in large numbers. By allowing the chips to have millions of transistors, circuits integrated are able to save space.

Two-way: A dual silicon controlled rectifier (SCR), triac is used to control alternating current (AC). Generally regulators used in lamps and contact, which controls the amount of electricity to reach a device.

Secondary transformer tapped: It is used for processing voltage, a plug-in transformer, the type of wall, changes from 120 volts AC at about 12 volts DC to the needs of small appliances. In involved a transformer secondary, the transformer secondary is connected to a cable so it can be used for multiple voltages, or more current.

Speaker: A loudspeaker converts electrical energy into sound energy.
