Ta yaya za a iya gano wutar lantarki da gwadawa?

A cikin da'irar lantarki, akwai abubuwa daban-daban da abubuwa daban-daban waɗanda ake buƙatar auna su. Wasu kayan aikin da za su iya auna waɗannan abubuwa daban-daban za su keɓanta da ma'auni ɗaya, amma da yawa za su haɗa ma'auni zuwa kayan aiki ɗaya. Abubuwan da za a auna sun haɗa da:

A halin yanzu

A halin yanzu ita ce kwararar wutar lantarki kuma ana auna amperes (amps, A). Na'urar da za ta iya auna halin yanzu ana kiranta da "ammeter". Don auna halin yanzu, na'urar aunawa dole ne a haɗa shi a jeri tare da da'ira ta yadda electrons su wuce ta cikin ammeter a daidai lokacin da suke wucewa ta kewaye.Halin halin yanzu na iya zama duka kai tsaye da mabambanta (m ko m). Wannan yana da alaƙa da yadda electrons ke motsawa ta hanyar kewayawa, ko dai kai tsaye; a daya hanya; ko canji; baya da baya.

Bambanci mai yiwuwa (voltage)

Voltage shine yuwuwar bambanci tsakanin maki biyu a cikin da'ira kuma ana samar da shi ta abin da muke kira tushen wutar lantarki a cikin kewaye; baturi ko soket na bango (mains wutar lantarki). Don auna ƙarfin lantarki, kuna buƙatar haɗa na'urar da ake kira voltmeter a layi daya da kewaye.

Tsayayya

Ana auna juriya a cikin ohms (ohms) kuma yana da alaƙa da yadda kayan madugu ke ƙyale halin yanzu gudana ta cikinsa. Misali, gajeriyar igiyar kebul ba ta da juriya fiye da dogon kebul saboda ƙarancin abu yana wucewa ta ciki. Na'urar da za ta iya auna juriya ana kiranta ohmmeter.

Yanzu, juriya da yuwuwar bambancin

Akwai dangantaka tsakanin volts, amps da ohms a cikin da'irar lantarki. Ana kiran wannan da dokar Ohm, wakilta ta triangle inda V shine ƙarfin lantarki, R shine juriya, kuma ni yanzu. Ma'aunin wannan alaƙa shine: amps x ohms = volts. Don haka idan kuna da girma biyu, zaku iya ƙididdige ɗayan.

Tushen wutan lantarki

Ana auna wutar lantarki a watts (W). A cikin sharuddan lantarki, watt shine aikin da ake yi lokacin da ampere ɗaya ke gudana ta cikin volt ɗaya.

Polarity

Polarity shine madaidaicin wurare masu kyau da mara kyau a cikin da'ira. A fasaha, polarity yana faruwa ne kawai a cikin da'irori na DC, amma tunda mains (AC) yana da waya ɗaya ta ƙasa, wannan yana haifar da zafi (rayuwa) da tashoshi masu tsaka-tsaki akan kwasfa da haɗin gwiwa, waɗanda za'a iya tunanin polarity. A matsayinka na gaba ɗaya, ana nuna polarity akan yawancin abubuwa (misali batura), amma yana iya zama dole a duba polarity akan wasu na'urori, kamar lasifika, inda aka tsallake su.Saboda gano polarity na iya haɗawa da bambancewa tsakanin tabbatacce da korau, da zafi da tsaka tsaki, akwai kayan aiki daban-daban waɗanda zasu iya bincika wannan, gami da na'urorin gano wutar lantarki da multimeters.

ci gaba

Ci gaba shine gwajin da'ira don sanin ko yana aiki ko a'a. Gwajin ci gaba yana nuna ko wutar lantarki na iya wucewa ta cikin abubuwan da ake gwadawa ko kuma idan kewaye ta karye ta wata hanya.

емкость

Capacitance shine ikon tantanin halitta don adana caji kuma ana auna shi da farads (F) ko microfarads (µF). Capacitor wani sashi ne da aka ƙara zuwa da'ira don adana caji.

mita

Mitar yana faruwa a cikin da'irori na AC kuma ana auna shi a cikin hertz (Hz). Mitar ita ce adadin juzu'i na madadin halin yanzu. Wannan yana nufin sau nawa yanayin halin yanzu ke canza alkibla akan lokaci ɗaya.
