Shaqada iyo xooggii hadda korontada

In circuit kasta u xiran yihiin si qasab heysta diinta tamarta double. In ka beddelid ah isha hadda laga sameeyey oo tamar kasta (tus, matoor - machining) galay tamarta korontada, iyo circuit hadda la mar kale beddelay qadarka u dhiganta tamarta si noocaas ah. Cabir circuit diinta hadda korontada ee ka mid ah noocyada kale ee tamarta - qiimaha hawlgalka hadda.

Laakiin waxaan fahamsanahay in shaqada iyo awoodda korontada hadda waa shuqulkii xoogga beerta korontada, dhaqaaqin soo oogay; sidaas darteed waa ay fududahay in xisaabi.

Shaqo on iibsiga la'aan korontada ee qiimaha beerta korontada lagu qiyaasay by sheyga wareejiyo by xaddiga lacag farqiga u dhexeeya iman kara dhibcaha bilowga iyo dhammaadka kala iibsiga, i.e. on danab ah:

A = qu.

Sida iska cad, ratio waxa laga yaabaa in ay ku habboon tahay qiimeynta fikradaha sida shaqada iyo awoodda korontada hadda. About size ee amarka, dhibtu ee silsiladda, waxaan u xukumi karaa by hadda ka dal ee Bannaanka, oo wakhtigii ay dhacdo, sida q = Waxaa.

Isticmaalka xiriirka noocan oo kale ah, waxaan ka heli formula ah muujiyaan qiimaha shaqada ee hadda on qayb ka mid ah oo kala duwan ee silsiladda, isagoo U danab ah:

A = UIt.

Shaqada iyo xoog of hadda korontada qiyaasay in jidka soo socda: haddii hadda qiyaasay in amperes, waqti seconds, iyo danab ee Volts, hawlgalka - in joules (J).

Sayidka, amperes 1 joule = 1 volt x 1 x 1 labaad.

Power waxaa lagu cabbiraa watts (W):

1 watt = 1 joule / 1 seconds, ama 1 watt amperes = 1 x 1 volt.

Su'aasha ah la xisaabinayo qiimaha shaqada ee hadda ka jirta aagga this gebi ahaanba la xidhiidhin su'aasha ah nooca tamarta ee tamarta korontada goobta soo jeedin doonaa. Shaqada Tani waa cabirka xoogga, beddelaa qaabab kale.

hawlgalka ku sidday hadda Electric kululeeyo kartaa nalalka buuxieyey, barafka Biraha, shaandheyn armature ee motor ah, ka dhigi qaab beddelidda kiimikada, iwm Shaqada iyo xooggii hadda korontada kiisaska oo dhan, loo ogaado heerka qaab beddelidda koronto galay qaabab kale - tamarta si farsamaysan, tamarta ee mooshinka kaamerada, iwm

Ogaanshaha in P awood = A / t ah, ka heli kartaa caanaha a by kaas oo awood u hadda waxaa loo xisaabiyaa at a silsilado site hal

P = UI.

Shaqada iyo xoog of DC loo xisaabin karaa iyadoo la isticmaalayo qaaciidooyinka kuwaas oo la ammeter, voltmeter. In dhaqanka, hawlgalka oo duurka korontada waxaa lagu cabbiraa qalabka gaar ah - counter. Isagoo maraya mitirka, gudaha ay bilowdo inay haddaba dhaqsada oo khafiifa disk aluminium, iyo xawaaraha wareeg ay si toos ah waa saami u amperage iyo danab. Tirada Kacdoonkii, kaas oo uu samayn doonaa markii qaar ka mid ah, caawin doonaa in go'aan fiican ee waqtigan shaqada. mitir korontada laga heli karaa guri kasta.

awood AC waxaa lagu cabbiraa iyadoo la isticmaalayo qalab gaar ah - meter xoog ah. In qalab ah qalab this lagu toosiyaa mabaadi'da voltmeter iyo ammeter.

qalabka korontada badan iyo qalab farsamo oo tilmaamaya in ay awood. . Tusaale ahaan, awooda waxaa laga yaabaa in lagu incandescent guluubka 25 W, 75 W, iwm, xoogga huufarka ah ama bir ah oo ku saabsan 1000 W, koronto ka gaari karin qiimaha aad u sarreeya - ilaa dhowr kun oo kilowatts. Xaaladdan oo kale, ay maskaxda ku hayaan awoodda hadda, kaas oo dhex mara qalab gaar ah.

Shaqada iyo awood AC yihiin xisaabiyaa si ka duwan. Sidaas darteed, si ay u xisaabiso shuqulka sameeyey by talantaalli hadda muddo waqti go'an, mid isticmaali kartaa caanaha:

P = 1 / 2I₀U₀ sababtoo ah φ. Inta badan isla'egta this ku qoran foomkan: P = IU sababtoo ah φ, halkaas oo aniga iyo U - qiyamka danab iyo hadda, taas oo ah 2 jeer ka yar qiimaha Ilodanimada baahisey.

formula ee xisaabinta awoodda AC waa la mid tahay sida DC ee.

Units tamarta iyo shaqada:

1 J 1 URA = 3600 J 1 Watt-labaad =;

Hectowatt 1 saac J = 360,000;

1 kWh = 3600000dzh.

Units xoogga,

1 ampere volt = 1 W;

1 hectowatt = 100 W,

1 kilowatt = 1000 watts.
