Mai waɗanda ita ce Yadda ake Samar da Yawan Ƙarshe na Sine na AC

Waɗannan su ne maimakon da ake tafi kan daga cikin karamin AC kada lokacin da ake yi aiki da AC.

Idan kana da karamin DC (figure – 1) na da shawarar da za a iya kwarshen shi a karamin AC. Ana samun duka abubuwa masu haka, amma babu shi ne voltage ta supply wanda yake zama AC supply voltage. Tana da shawarar zuwa wannan lura cewa yadda ake zaba voltage ta AC supply don haka za ta yi waɗannan aiki daidai da karamin DC.

A zabe voltage ta AC supply (AC Vpeak = 10 volt) da ke cikin karamin DC. Idan ake yi haka, za a iya nuna (figure 3) cewa a halin yaduwa, AC voltage signal ba ya fi sanya al'adu da constant DC voltage (al'adu mai birni), wanda yana nufin cewa AC signal ba zan iya bayyana amsa sama da voltage ta DC supply.

Wanda yana nufin cewa muna da shawarar saurari voltage ta AC don in sanya al'adu da kuma neman hakan cewa an samu amsa sama da voltage ta DC.

An samu cewa (figure 4) idan ake saurari peak voltage Vpeak zuwa (π/2) karamin voltage ta DC supply voltage, ana iya sanya al'adu da DC a AC. Idan AC voltage signal yana nuna voltage ta DC signal, wannan irin value ta DC signal yana amsa average value ta AC signal.

Don haka, voltage ta AC ya kamata bayyana amsa sama da power. Amma idan an fara supply, an samu cewa AC voltage ta bayyana power da ya fi yawa da DC. Saboda average value ta AC ta bayyana amsa charges, amma ba amsa power. Don haka, don in samu amsa power daga AC supply, muna da shawarar rage voltage ta AC supply.

An samu cewa idan ake rage peak voltage Vpeak zuwa √2 karamin voltage ta DC, za ta samu amsa power a duk biyu. Idan AC voltage signal ta bayyana amsa power da voltage ta DC, wannan irin value ta DC voltage yana amsa root mean square ko rms value ta AC.
A nan ake buƙaci game da yadda ake neman power daga karamin, baki ɗaya da yadda ake neman electrons. Saboda haka, a gaba daya ake amfani da rms value ta AC supply, ba average value ba, a duk karamin AC.

Koɗa
Average value ta AC current yana nuna amsa charges a karamin DC current.

RMS value ta AC current yana nuna amsa power a karamin DC current

AC current yana neman charges da dama don in bayyana amsa power ta DC.
