Application of semiconductor in electronic circuit
1.1 Rectifier diodes pn-junction diodes is used to change the alternating current is direct current. Based on the principle that electricity will flow through the diode when different rank that p-type positive only
1.2 Zener diodes is diode special to use reveres control C voltage drop it to voltage fixed;The principle is when put reverse bias in diode high enough to cause the breakdowe make electricity back very high flow through diode go this flowing stream. Voltage constant
1.3 Transistor
using open, closed Switch or extended electricity
