Daban-Daban na Manyan Turon Resisita a Farko (Kuma Yadda Ake Amfani Da Su)
Mai shi ne Resistor?
Resistor ya shi kompoonenti masu aiki a cikin kabilu wanda yake ba da resistance ga cashi na current. Akwai abubuwa daban-daban daga cikin resistors. Wadannan resistors suna faɗa a cewa ainihin aikinsu, ainihin tafiyar da suka rarrabe da ainihin parametosu (kamar hawa da karamin sana'ar). Abubuwan da ake samun a cikin resistors sun hada da:
Carbon Composition Resistor
A carbon composition resistor (ko kuma carbon resistor) ya shi kompoonenti masu aiki a cikin kabilu. Wadannan resistors suna da sadarwa da kuma ake yi a gaba da kyau.
Carbon resistors suna da mutanen da ake zama da carbon clay composition da kuma case mai plastic. Lead na na resistor ya shi da tinned copper.
Abubuwan da ake so kuwa da wadannan resistors sun hada da cewa ake samu a gaba, da sadarwa, da kuma ma ake iya gudanar da su.
Wadannan resistors suna da muhimmanci a cikin kitokoki Arduino da ke da damar da ake samu a gaba.
Babban matsalolin da ake so kuwa da carbon composition resistors shine cewa su suna da tsari a gaba da hawa. Tolerance range na resistance na carbon composition resistor ya shi ± 5 zuwa ± 20 %.
Duk da cewa wannan ba za a yi lalace ba a kan duk wasu ayyukan electronics projects da ake yi a gida.
Wannan type na resistor yana da yawan da ake samu electric noise saboda passage da electrical current daga wata carbon particle zuwa mafi.
Idan sadarwa ce babban al'amur da ake yi a cikin designing a circuit, wadannan resistors suna amfani da su.
Carbon resistors suna da bandon da ake fada a cikin body cylindrical. Wadannan bandon suna da code don values na resistance na resistors da tolerance range.
Thermistor
Kalmomin thermistor ya nufin thermal resistor. Value na resistance yake zai canza idan hawa ta canza.
Yawan thermistors suna da negative temperature coefficient wanda yake nufin cewa resistance yake zai rage idan hawa ta ci gaba.
Wadannan suna zama da semiconductor materials. Resistance da za a iya samu daga thermistors ita ce megaohms.
Su ake amfani da su don in tabbatar da hawan hawa, idan hawa ta canza, resistance yake zai canza.
Wire Wound Resistor
A wire wound resistor wire na manganin ko constantan yana zama a cikin cylinder na insulating material. Temperature coefficient of resistance na manganin da constantan yana da zero. Don haka, resistance variation with temperature na wannan resistors yana da yawan da ya rage.
Wounded wire yana da cover mai insulating material da ya zama heat resistible. Wannan cover yana da yawan da ya rage effect of ambient temperature variation.
Different sizes and ratings of wire wound resistors can easily be achieved by using different lengths and diameters of the wire.
Wadannan resistors suna da ratings da yake da damar da ake samu. Range na resistance values yana rage daga 1 Ω zuwa 1 MΩ.
Tolerance limit na wadannan resistors yana rage daga 0.01 % zuwa 1 %. Su ake amfani da su don high power applications da 5 zuwa 200 W dissipation ratings.
Sadarwa na wadannan resistors yana da yawan da ya rage da carbon resistors. Idan carbon composition resistor ba za a iya tabbatar da aiki ba saboda limitations, ake amfani da wire wound resistor.
Babban matsalolin da ake so kuwa da wannan resistor shine inductance wanda yake faru saboda structure na coil-like. A high frequency, behavior na circuit zai canza saboda reaction.
