Katundu pulagi kunyumba

Katundu foloko - izi ndi chipangizo kuti chofunika kuti titsimikize ndi kudziwa boma mlandu uliwonse zitini batire. Ndi zamphamvu katundu resistor ndi DC voltmeter, ndi probes awiri. ziziyenda ambiri kutsegula foloko kukayendera batire ndi wothandizira zazikulu mabatire yokonza. Komabe, m'masitolo chipangizo izi mtengo ndithu. Choncho, ife kutipatsa malangizo a mmene kutsegula pulagi wapangidwa ndi manja awo.

Chinthu choyamba chimene muyenera kulingalira - umu ndi mmene voteji kwambiri ayenera kwathunthu mlandu batire banki yeniyeni. Tikutero mu bukhuli. China chimene muyenera kuonetsetsa kuti batire kupeza mabanki payekha.

Tsopano anatengedwa microammeter ndi mndandanda ndi resistor a. Kulimbikira akhale zikuluzikulu pang'ono kuposa voteji a mabanki batire. Tsopano kusintha lonse chipangizo ndi munthu watsopano, amene ayenera tsopano azigwirizana, kutsatira voltmeter chifukwa kusintha DC voteji ku polarity ankafuna. The voteji kuti umagwiritsidwa ntchito pa calibration, m'pofunika kulamulira chitsanzo chipangizo.

malangizo ena a batire n'kofunika kudziwa mlingo mwadzina kapena pazipita katundu panopa. Tsopano, kumasulira mfundo zonse magawo mu dongosolo SI, zotsatira zathu zimapezeka mu dongosolo lomwelo. Komanso patsogolo kulimbikira katundu resistor kotero: R = U / I - momwe R akukana mu ohms, mtengo wa U ndi voteji mu mayunitsi a volts, ndipo potsiriza I - mwamphamvu panopa ali amperes. Mu dongosolo ili m'pofunika mmalo mtengo wa voteji a banki munthu, osati batire.

Ndiye ife kugwira ntchito zowerengetsa mphamvu imene allocated kuti resistor monga mwa chilinganizo P = UI. Kodi P - mphamvu Watts, U - ndi voteji mu mayunitsi a volts, ndipo potsiriza I - ngati chotikakamiza ziliri pa amperes. Sankhani mphamvu mlingo wa katundu resistor kuposa amene waima kuchokera osiyanasiyana muyezo. The resistor ayenera kukhala waya.

Tsopano tengani mayeso kumabweretsa athe kulimbikitsa panopa likuyenderera mu resistor lapansi. Ife kulumikiza iwo thereto mwa mawaya kuti akhoza kulimbana mwachindunji panopa. Onetsetsani kuti muyenera wabwino mfundo solder.

Pa nthawi imeneyi katundu foloko ndiye kuti Sali okonzeka. Polumikiza voltmeter (ammeter chikugwirizana pa mndandanda ndi resistor zing'onozing'ono) limodzi ndi katundu. Tsopano muyenera kudziwa polarity wa probes, ndi polarity zofanana m'gulu voltmeter. Komanso ndikofunikira kupeza zolumikizanazo.

Ndipotu izi, ife kukonza mfundo zonse pa refractory, zokutira zitsulo, chimango okhwima, umene anapereka ndi chogwirizitsa. Probes ayenera kuyikidwa kuti mtunda wa pakati pawo anali wofanana ndi mtunda pakati pa zitini malo.

Katundu pulagi sayenera chikugwirizana ndi batiri. Inu simungakhoze kuchita izo pafupi milandu ina batire. Ngati njira wasiya posachedwapa, mokwanira ventilate m'deralo. Tsopano kutsegula pulagi ndi chikugwirizana aliyense banki nayenso.
