Electron yuan the study of parts of an apparatus, it is every friend that learns an electron, a doorsill that must experience, ceaseless geoscience reviews ability progresses ceaselessly. The article is worn yuan of parts of an apparatus such as resistor, capacitance, potentiometer, dynatron, diode, silicon controlled rectifier, introduce one by one to everybody.

 

Show parts of an apparatus or stuff are right block up action of electric current. In dc road, resistance is equal to voltage drop to divide the electricity that carries with place. The resistor of lead depends on the property of area of its length, cut and material. Metallic resistance is the least, the resistance of dielectric is the greatest. The main unit of resistor is ohmic, abbreviation Europe. Use the electronic component that equipment or material make to block up action of electric current.

I=U/R (Ohm’s law: ? The resistor that broadleaf plant of Piao of afterwards of  of Gou of Si of male of afterwards Lu instrument says to Miao Gou burns  ? to follow conductor becomes inverse ratio)

 

The characteristic of the electric current in I=I1+I2+…+In (parallel circuits: The electric current on dry road is equal to the sum of electric current of each spur track)

 

U=U1=U2=…=Un (the characteristic of the voltage in parallel circuits: Each spur track two upright voltage are equal. Be equal to power source report

Laden capacitance can make proper adjustment according to particular case, through adjusting general and OK move the working frequency of resonator nominal value.

 

Potentiometer is to have value of 3 terminals, block to be able to press some kind of change the resistor component of regular adjustment. Potentiometer is comprised by resistor body and portable brush normally. When system of brush edge resistor is mobile, in output end obtains the resistance that measures particular concern with displacement or voltage namely.

 

Potentiometer can make 3 upright component use already also can make two-terminal component is used. Latter can inspect one rheostat, because its action in circuit is to obtain with input voltage (extra voltage) the output voltage that becomes particular concern, it is potentiometer because of what this says.

Dynatron, full name should be semiconductor dynatron, also say ambipolar model dynatron of transistor, crystal, the semiconductor device that is electric current of a kind of control its action is a faint signal enlarge is worth larger telegraphic number into extent, also use as without contact switch. Crystal dynatron, it is semiconductor basic one of yuan of parts of an apparatus, have voltaic enlarge effect, it is the core component of electronic circuit. Dynatron is in a semiconductor base piece on make the PN ties with two very close apart, two PN knot distributes whole semiconductor into 3 parts, intermediate part is base area, two side part is emissive area and market cable division, arrange means to have PNP and NPN two kinds.

Diode, (English: Diode) , among electronic component, one kind has the unit of two electrode, allow electric current to had flowed by single way only, a lot of use is the function that uses its commutate. And transfiguration diode (Varicap Diode) use regard as of electronic type adjustable capacitor. The electricity that major diode has is directional we say normally for “ commutate (Rectifying) ” function. The function with the most general diode allows electric current to be passed by single way only namely (call suitable to bias voltage) , retrorse when block is broken (call converse bias voltage) . Accordingly, diode can consider electronic edition go against stop a powerful person.

Silicon controlled rectifier calls brilliant brake the canal again (Silicon Controlled Rectifier, SCR) . Since 20 centuries one had developed since 50 time are published big familial, its main member has one-way brilliant dam up water canal of canal of canal, two-way brilliant brake, smooth brake accusing brilliant, go against guide brilliant brake is in charge of, but brake of canal of brake of silicon controlled rectifier, fast brilliant is in charge of Guan Duanjing, etc.
