- Kirchhoff cov ua ntej txoj cai - cov txoj cai sib txuas . Cov sum ntawm tag nrho cov tam sim no nkag mus rau a kev sib tshuam yuav tsum sib npaug ntawm tag nrho cov tam sim no tawm hauv kev sib tshuam : ∑Iin = ∑Iout.
- Kirchhoff cov thib ob txoj cai - cov txoj cai voj . Qhov algebraic sum ntawm cov kev hloov pauv hauv qhov muaj peev xwm nyob ib puag ncig ib puag ncig kaw Circuit Court txoj kev ( lub voj ) yuav tsum yog xoom: ∑V = 0.
Ib yam li ntawd, txoj cai voj voog yog dab tsi?
Kirchhoff cov Txoj Cai Loop Formula. Hauv ib qho " lub voj "ntawm ib lub voj voog kaw, tuaj yeem muaj ntau yam ntawm cov khoom siv hluav taws xob, xws li roj teeb thiab cov khoom tiv thaiv, qhov sib npaug ntawm qhov sib txawv ntawm qhov sib txawv ntawm tag nrho cov ntsiab lus Circuit Court yuav tsum yog xoom. Qhov no yog hu ua Kirchhoff's. Txoj Cai Loop . Voltage sib txawv yog ntsuas nyob rau hauv Volts (V).
Tsis tas li ntawd, Kirchhoff txoj cai junction yog dab tsi? Kirchhoff's junction rule hais tias thaum twg los tau kev sib tshuam (node) nyob rau hauv ib qho hluav taws xob Circuit Court, cov sum ntawm cov dej ntws mus rau hauv uas kev sib tshuam yog sib npaug rau cov sum ntawm cov dej ntws tawm ntawm qhov ntawd kev sib tshuam.
Ua raws li qhov no hauv kev txiav txim siab, koj ua li cas sau ib lub voj sib npaug?
Rau sau nqes a kev sib npaug , koj xaiv qhov pib taw tes, thiab ces taug kev ncig lub lub voj nyob rau hauv ib qho kev taw qhia txog thaum koj rov qab mus rau qhov chaw pib. Thaum koj hla cov roj teeb thiab cov resistors, sau down txhua qhov hloov pauv voltage. Ntxiv cov voltage nce thiab poob thiab teem lawv sib npaug rau xoom.
Kirchhoff's 3 txoj cai yog dab tsi?
Qhov sib txawv ntawm cov spectra no thiab cov lus piav qhia ntawm yuav ua li cas tsim lawv tau sau tseg hauv Kirchhoff peb txoj cai ntawm spectroscopy: Ib qho luminous khoom, kua, los yog roj ntom ntom emits lub teeb ntawm tag nrho cov wavelengths. Ib tug uas tsis muaj kev ceev, kub roj pom tawm tsam ib tug txias tom qab emits ib tug kaj LINE los yog emission LINE spectrum.

Koj yuav daws qhov kev sib npaug plaub npaug li cas siv txoj cai null factor?
Los ntawm qhov no peb tuaj yeem suav tias: Yog tias qhov khoom ntawm ob tus lej yog xoom, ces ib lossis ob tus lej yog xoom. Ntawd yog, yog tias ab = 0, ces a = 0 lossis b = 0 (uas suav nrog qhov ua tau tias a = b = 0). Qhov no hu ua Null Factor Law; thiab peb siv nws ntau zaus los daws qhov sib npaug ntawm plaub fab
Yuav ua li cas koj daws qhov zoo tagnrho gas txoj cai?
Txoj Cai Kev Cai Roj Hmab Zoo Tshaj Plaws Cov Lus Nug Gas Txoj Cai Cov Lus Nug: Teb: Qhov Volume yog V = 890.0mL thiab qhov kub yog T = 21 ° C thiab qhov siab yog P = 750mmHg. PV = nRT. Teb: Tus naj npawb ntawm moles yog n = 3.00moles, kub yog T = 24 ° C thiab siab yog P = 762.4 mmHg. PV = nRT
Koj yuav daws tau txoj cai exponent li cas?
Tsuas yog txav cov exonents tsis zoo. Product Rule: am ∙ an = am + n, qhov no hais tias kom muab ob lub exponents nrog tib lub hauv paus, koj khaws lub hauv paus thiab ntxiv lub hwj chim., qhov no hais tias kom faib ob exponents nrog tib lub hauv paus, koj khaws lub hauv paus thiab rho tawm lub hwj chim
Yuav ua li cas koj daws Descartes txoj cai ntawm cov paib?
Descartes txoj cai ntawm cov paib qhia peb tias qhov peb tom qab ntawd muaj 3 qhov zoo tiag tiag lossis tsawg dua tab sis tus lej khib ntawm xoom. Yog li peb tus naj npawb ntawm qhov zoo zeros yuav tsum yog 3, lossis 1. Ntawm no peb tuaj yeem pom tias peb muaj ob qhov kev hloov pauv ntawm cov cim, yog li peb muaj ob qhov tsis zoo lossis tsawg dua tab sis ib tus lej zeros
Koj tuaj yeem siv txoj cai khoom siv tsis yog txoj cai quotient?
Muaj ob qhov laj thawj vim li cas txoj cai quotient tuaj yeem ua tau zoo dua rau txoj cai tswj hwm lub zog ntxiv rau cov khoom lag luam hauv kev sib txawv ntawm cov quotient: Nws khaws cov denominators thaum simplifying qhov tshwm sim. Yog tias koj siv txoj cai fais fab ntxiv rau cov khoom siv, feem ntau koj yuav tsum nrhiav ib tus lej sib piv kom yooj yim rau qhov tshwm sim
