Me ke nufin da Voltage Source?

Voltage source yana amsa wani zabi mai taimaka da shi a kula da energy zuwa circuit. A cikin harsuna, ya kai a matsayin karamin jiki da take suka da elektronon da za su yi lalacewa a tsari. Yana daga cewa mafi yawan ruwa a kan systemi, amma wannan pump na a yi wa elektronon a tsarin. Wannan voltage source yana amfani da shi a cikin abubuwan electronic da systemi.

Voltage source yana faru ne a matsayin zabi da biyu terminal, cewa yana da biyu wurare don kula - wanda ake kula da elektronon da kuma wanda ake kula da sauran. Wannan siffar da take amsa yana da muhimmanci a cikin amfani da electric power, inda yake kula da abubuwan da ka aiki da su daga telefonin zuwa kitchen appliances.

Abun Abun Voltage Sources

Abun abun voltage sources sun hada:

Independent Voltage Source: Sun hada biyu subtypes - Direct Voltage Source da Alternating Voltage Source.
Dependent Voltage Source: Sun hada biyu subtypes - Voltage Controlled Voltage Source da Current Controlled Voltage Source.

Independent Voltage Source

Independent voltage source yana iya bayar da voltage (fix ko variable a lokacin) zuwa circuit kuma ba a yi amfani da wani abu ba a cikin circuit.

Direct Voltage Source ko Time Invariant Voltage Source

Wani voltage source da yake iya bayar da constant voltage a matsayin output ana amsa a matsayin Direct Voltage Source. Lallacewa da elektronon yana zama a matsayin yanayi. Lallacewa da currents yana zama a matsayin yanayi. Volumen da voltage yake zama ba zai canzawa a lokacin. Misali: DC generator, battery, Cells etc.
independent voltage source

Alternating Voltage Source

Wani voltage source da yake iya bayar da alternating voltage a matsayin output ana amsa a matsayin Alternating Voltage Source. Hakan, polarity ta zama a bincike a lokutan da ake daidaito. Wannan voltage yana taimaka da current yana lallacewa a matsayin yanayi a lokacin da kuma a matsayin yanayi a lokacin. Cewa yana zama time-varying. Misali: DC to AC converter, alternator etc.

Dependent ko Controlled Voltage Source

Wani voltage source da yake iya bayar da output voltage wanda ba a yi amfani da wani abu ba a cikin circuit kuma yana da dependency a kan voltage ko current a wata wurin circuit ana amsa a matsayin dependent voltage source.

Sun da sabuwar terminal. Idan voltage source yana da dependency a kan voltage a wata wurin circuit, akwai wadannan amsa a matsayin Voltage Controlled Voltage Source (VCVS).

Idan voltage source yana da dependency a kan current a wata wurin circuit, akwai wadannan amsa a matsayin Current Controlled Voltage Source (CCVS) (a nan a figure below).
dependent or controlled voltage source

Ideal Voltage Source

Voltage source yana iya bayar da constant voltage zuwa circuit kuma yana amsa a matsayin independent voltage source saboda haka yana independent da current da circuit yake kula. Volumen da internal resistance yana zama zero. Wannan yana cewa ba a yi waste da power ba saboda internal resistance.

Babu lokacin da load resistance ko current a cikin circuit, wannan voltage source zai bayar da steady voltage. Yana aiki a matsayin 100% efficient voltage source. Duk voltage da ideal voltage source yake bayar zai drop perfectly zuwa load a cikin circuit.

Don fahimtar ideal voltage source, zan iya bayar da misali a cikin circuit a nan. Wani battery a nan yana amsa a matsayin ideal voltage source wanda yake bayar da 1.7V. Internal resistance RIN = 0Ω. Resistance load a cikin circuit RLOAD = 7Ω. A nan, za a iya samun cewa load zai bayar da duk 1.7V na battery.
