Ndi mitundu yosiyanasiyana ya resistors Kodi

Polenga luso zithunzi mfundo zofunika. Resistors ali mwa zofunika kwambiri. N'zovuta kulingalira chiwembu madera asanu, kulikonse kumene kupeza ntchito yawo.

ndi resistor Kodi

Mawu akuti analengedwa chifukwa cha Latin "Resisto", sipangakhalenso likumasuliridwa kuti "kupewa." Waukulu chizindikiro deta zinthu, amene amathandiza chidwi ndi kukana mwadzina. Iwo amayezedwa ohms (nambala ya ohms). mfundo mwadzina zikusonyeza chipangizo nyumba. Koma chithunzi chenicheni angakhale osiyana pang'ono. Childs, nuance izi zikuphatikizapo kugwiritsa ntchito makalasi ndi tolerances mwatsatanetsatane. Izi tikambirana. Ngati simungathe kumvetsa chinachake za mitundu ya resistors, chithunzi kuthandiza kukonza.

Makalasi molondola ndi tolerances

Ambiri, makalasi kwambiri chidwi. Iwo zitatu:

1. Choyamba. Imakhala kwa zolakwika peresenti mpaka asanu anati phindu mwadzina.
2. Chachiwiri. Imakhala kwa zolakwika zomwe angafikire chakhumi cha mtengo mwadzina.
3. Chachitatu. Izi zikuphatikizapo mabomba kuti kukula zolakwika angafikire peresenti makumi awiri kufunika mwadzina.

Ndipo zimene ngati zolakwika lalikulu n'zosayenera? Pali resistors mwatsatanetsatane zimene zimapereka maganizo a munthu pazipita kusiyana:

1. 0.01%.
2. 0,02%.
3. 0,05%.
4. 0.1%.
5. 0.2%.
6. 1%.
7. 2%.

asadziphe

Chofunika kwambiri amafotokozera kusankha kwa magawo dera ali Kuchepetsa voteji ntchito mphamvu mwadzina madyaidya ndikuledzera ndi kutentha koyefishienti kukaniza. Chithunzi yamasika limasonyeza bwanji kusintha mlingo lonse zidzakhudza ntchito chipangizo. Mu chithunzi ichi akhoza kuchuluka kapena kuchepa malinga ndi kugwiritsidwa ntchito mu kupanga lapansi. Yoyezedwa mphamvu madyaidya ndikuledzera amasonyeza malire mchitidwe ntchito. Ngati kotunga khalidwe ndi wamkulu kuposa angathe kukonzedwa, ndi resistor akhoza kungoyankha kuwotcha kunja. Ndi Kuchepetsa voteji ntchito kuzindikira chizindikiro amenewa, mmene ntchito yodalirika zida adzakhala anapereka.

The mitundu ikuluikulu ya resistors

Iwo anayi:

1. Non-malamulo:

a) zonse.

2. mulibe malamulo oletsa:

a) chepetsa;

b) zosintha.

3. Thermistors.

4. Photoresistors.

Mulibe malamulo oletsa resistors atathana zina ogaŵikana palibe waya /. Mu mtundu yamasika zina bala waya kuti ndi lalikulu resistivity. Kusonyeza resistors anakonza mawonekedwe a rectangles, umene ndi mfundo zenizeni. Mtengo wa kololeka mphamvu madyaidya ndikuledzera ali chinanena mu chithunzi zojambula. Ngati mtengo kulimbana ndi mu osiyanasiyana ohms 0 kuti 999, mayunitsi muyeso si ambiri mwasankha. Koma ngati chithunzi ichi zoposa zikwi, kapena miliyoni, ndi mayina ntchito ohms ndi megohms, motero. Ngati chithunzi anasonyeza okha kapena mwina kusintha pa zoikamo, kuwonjezera *. Chifukwa cha mitundu mosiyana ndi resistors magawo mosavuta amasiyana.

zinthu variable

Tipitirize kuganizira mitundu ya resistors. Mtundu wa chipangizo akhoza kutchedwa variable. Iwo kukana akhoza osiyanasiyana monga ziro kufunika mwadzina. Akhozanso / waya. Yoyamba ndi ❖ kuyanika conductive kuti umagwiritsidwa ntchito pa mbale dielectric monga Arc, ndi momwe kukhudzana ndinapirira n'kufuna kuti yakwera chitsulo chogwira matayala a. kayendedwe ake ikuchitika ngati n'koyenera kusintha mtengo kukana. Malinga zingapo zochititsa zochitika za izi zikhoza kusintha mu kuchita zimenezi:

1. Liniya.
2. Logarithmic.
3. Kwakukulu kwambiri.

resistors Trimmer

Iwo alibe olamulira projecting. Kusintha magawo a mtundu wa resistors zimatheka ndi screwdriver kapena basi / makina chipangizo tikhoza kuchita ntchito yake. Izi ndi mitundu ina ya m'mbuyomu resistors ntchito pa nthawi imene munthu ali ndi mphamvu zonse iwo Mwachitsanzo, okamba.

thermistors

Chotero anaitana zinthu michenga yopangira zida zamagetsi, pamene dera magetsi imene chizindikiro monga kukana zimasiyanasiyana ndi kutentha. Pamene adatchithisira kuchuluka kwake. Ngati kutentha amachepetsa, kulimbikira kumawonjezera. Ngati ndondomeko pamapindikira chimatsatira mbali imodzi (magnification ukuwonjezeka), ndiye amatchedwa PTC amafotokozera.

photoresists

Chotero anaitana zinthu, imene chizindikiro index zimasiyanasiyana mchikakamizo cha kuwala (ndi zina, ndipo mu atomu) cheza. Monga ulamuliro, ntchito photoresists ndi zabwino photoelectric kwenikweni. kukana kwawo amachepetsa pamene amachitiridwa kuwala. Photoresists ndi mamangidwe mophweka, kukula yaing'ono ndi mkulu tilinazo, amene amalola ntchito zawo photoelectric, owerengera, ulamuliro, malamulo ndi kulamulira zipangizo, masensa ndi zipangizo zina zambiri.

Pomaliza

Apa pali resistors amenewa, mitundu, cholinga, mfundo ya ntchito zipangizozi.
