Magetsi. mphamvu panopa

Kuphunzira magetsi monga chodabwitsa thupi akuyamba ngakhale kusukulu. aphunzitsi ambiri, ana wosalira kumvetsetsa nkhaniyo poyerekeza adasonkhananso kwa magetsi mu kondakitala ndi gulu la madzimadzi kudzera chitoliro lapansi. Ngakhale chitsanzo ichi ndiyopenekela schematically akadali amalowerera kufotokoza njira kugwirizana ndi chodabwitsa cha magetsi ambiri ndi magetsi inawadutsa loyenda mu wochititsa makamaka. Koma, ikusonyeza kuchita, zimakhala zosavuta kuphunzira ins ndi outs kwa gawo lalikulu la sayansi, ngati inu kuganizira njira zenizeni zikuchitika popanda kuyesa kupeza mnzake dzikoli zodabwitsa makina.

Kulongosola zochitika magetsi kunachitika akuwauza, gwiritsani ntchito ndi zosiyana zosintha ndi magawo. N'zoona kuti tiligwiritse ntchito ndife za magetsi mphamvu panopa, koma mtima wa chizindikiro ichi adzakomana makhalidwe ena waukulu otaya magetsi wochititsa lapansi.

mphamvu la makhalidwe ofunika ya magetsi. Ndi kukhala thupi izo zikusonyeza kuchuluka kwa magetsi (kuchuluka kulipidwa), dera magetsi wakupambana mu nthawi unit. Kuti izi n'komwe kuchuluka kwa woyang'anira magetsi yomwe wopyoza gawo mtanda pa nthawi unit. Mu mawonekedwe masamu, phindu uyu amaoneka ngati m'khosi (cl) ogaŵikana chachiwiri (s). Kwa wina muyeso panopa anatengedwa ukulu ampere (A).

The chizindikiro lotsatira kuti n'komwe pamene kuwerengetsa panopa mphamvu voteji ndi. Popeza kuti magetsi - ndi kayendedwe mwadongosolo. particles ndi mlandu kulenga kayendedwe zoyenelera kukhala ndi munda magetsi. Choncho, voteji kudziwika phindu kuchita masamu chiŵerengero cha machitidwe panopa pa mbali imodzi ya unyolo mlandu likuyenderera mu izo. Unit wa voteji, anaganiza kutenga volts (V), ndilo chiŵerengero cha wagawo thupi la ntchito pa wagawo mlandu J. CL.

Ntchito ammeter olumikizidwa kwa dera zino, kudziwa kukula kwa mphamvu panopa, ndi voltmeter olumikizidwa ku kufanana - voteji. AC mphamvu tsopano anatsimikiza analytically ndi kuchulukitsa zimakhudzanso voteji lapansi. Poganizira kale analandira thupi chizindikiro kudziwa kupeza mphamvu wagawo J / s kapena Watt chimodzi (W). Zochita takambirana chitsanzo cha mawerengedwe a mu nkhani yabwino amene anatsimikiza DC mphamvu.

Ndi zambiri monga kuchita tsiku ndi tsiku tikulimbana ndi atatu gawo panopa. Tingadziwe mphamvu ya zitatu gawo panopa ngati Uwerenge ubongo gawo lirilonse munthu. Popeza kuti aliyense wa iwo ukugwira ntchito AC mode, mphamvu chinthu mawerengedwe anawonjezera kuti katundu mphamvu chinthu Ko j.

Poganizira okwana mphamvu zatsopano njira zosiyanasiyana polumikiza katundu ndi atatu-gawo zikusinthira (ndipo ife tikudziwa pali awiri - makona ndi nyenyezi), tikuona kuti pambuyo losavuta masamu kusintha chilinganizo kwa mawerengedwe milandu onse anatenga maganizo. Kuti mankhwala a voteji mphamvu mzere panopa ndi mphamvu chinthu Ko J accrue katundu chinthu wofanana ndi muzu lalikulu la zitatu (kapena, mu pafupifupi mawerengedwe 1,73).

Atafufuza mfundo yonena za "mphamvu imeneyi" ayenera kukumbutsidwa kuti pali mitundu iwiri chachikulu cha izo. Pakuti yogwira mphamvu magetsi yodziwika ndi kutembenuka mu njira zina mphamvu. Kungakhale kuwala, ikukhudzana makina ndi ena. Ntchito kuyeza Watts, kilowatts, megawatts.

Tikaonetsetsa zotakasika mphamvu ya magetsi zikutanthauza mtengo, yodziwika ndi mtolo magetsi, mphamvu analengedwa ndi Phokoso la m'thengo mu atomu ndi ogula. Nthawi zambiri, mtundu uwu wa mphamvu ndi khalidwe la injini. Monga mayunitsi kutenga volts - amperes zotakasika (var).
