Amplifying circuit is used in most electronic devices, such as audio-frequency amplifier circuit in cassete, amplifiers, amplify the signal in the color television video, etc. ..
In the electronic circuits of devices such as Radio-Cassette, Amlpy, color TV, VCD, etc. ... we use a DC power at different voltage levels, but outside of the devices plugged Zac is back plugs directly into 220V 50Hz AC power, so the electronics needed to convert a part from AC to DC voltage supply for the circuit on, converters include:
1. Atomic Structure:To understand the current nature we know that ( knowledge of high school ) all the elements are constructed from atoms and each atom of a substance is composed of two parts
1 - The concept of alternating current power line is alternating currents in the afternoon and value changes over time, these changes often circulating in a certain period.
Field Effect Transistor Mosfet is ( M etal O xide S emiconductor F ield E ffect T ransistor) is a special Transistor structure and operations other than conventional transistors that we know, the Mosfet is the principle of operation based on performance chain from field to generate electricity, the components have a large input impedance preferred to amplify the weak signal source, Mosfet is used more in the Monitor power circuit, the source computer.
Three layers of semiconductor transistors coupled together to form two connection PN junction, if the transplant in order to be PNP Transistor we agree, if the order pair NPN transistors have been back. in terms of structure Diode Transistor equivalent to two oppositely game.
Inductors are a number of coils wound into multiple loops, winding painted emay insulating core coil may be air, or a conductive material such as ferrite or steel cores from the techniques.
Capacitors:Capacitors are passive electronic components widely used in electronic circuits, they are used in the source filter circuit, noise, signal ac circuit, oscillator circuit. etc. ...
1.1 - What is a Semiconductor?quality semiconductor materials to produce all kinds of semiconductors such as diodes, transistors, IC we have seen in electronic devices today.
Resistance is What I understand simple - resistance is the resistance of a power line conductor, if a good conductor of electricity, the resistive small, poor electrical conductor, the greater the resistance, electrical insulators, the resistance is extremely large.
Many of you training to "fix hardware" such as ATX power supplies, CRT monitor, LCD, printer, motherboard, laptop ... but do not know anything about electronics?
