Mutoro chivhariso pamba

Mutoro forogo - iri zano kuti kunodiwa kuziva uye kuona mamiriro vebasa rimwe bhatiri magaba. Iri simba mutoro resistor ane DC voltmeter, uye vaviri Yatanga Kuongorora. vatyairi vazhinji Takudzai forogo kutarisa bhatiri ndiye mubatsiri kukuru yokuzvigadzirisa mabhatiri. Zvisinei, muzvitoro mudziyo uyu zvikuru zvinodhura. Saka, Tichavonga mirayiridzo sei vapinze chivhariso yakaitwa nemaoko avo pachavo.

Chinhu chokutanga chaunofanira kufunga - ndiwo zvakadini voltage kunofanira ari zvizere mhosva bhatiri kubhengi chaicho. Izvi zvinoratidzwa redzidziso. Else unofanira nechokwadi chokuti bhatiri ane kuwana nomumwe mabhanga.

Ikozvino atora microammeter uye ngaatevedzane ine resistor. The nemishonga inofanira kuva zvishoma yakakura kupfuura voltage ane bhatiri mabhanga. Zvino kushandura rapanzvimbo mudziyo mutsva uya zvino anofanira calibrate, nokushandisa zvichiguma voltmeter achichinja DC voltage kuti achida polarity. The voltage kuti rinoshandisirwa panguva calibration, zvinokosha kudzora mudziyo womuenzaniso.

Mimwe mirayiridzo yacho bhatiri zvinokosha kuziva mwero chezita kana kufadza mutoro ano. Zvino, kushandura parameters zvose tsika vari SI ino, migumisiro edu avapo ari chete ino. Humwe mberi nemishonga yacho mutoro resistor saka: R = U / I - sezvamakaropafadzwa R ndiye mumweya ohms, kukosha U ndiyo voltage mu vamapoka volts, uye pakupedzisira I - kuitika kuchinyanya riri amperes. In fomura ichi zvakafanira kutsiva kukosha voltage mumwe pamahombekombe, kwete bhatiri.

Zvadaro isu compute simba riri dzinounzwa kuna resistor maererano nzira P = UI. Apo P - simba muna Watts, U - ndiye voltage mu vamapoka volts, uye pakupedzisira ini - ndichaita kumanikidza kuitika mune amperes. Sarudzai simba Rating pamusoro mutoro resistor kupfuura chimwe chete chinokunda kubva mureza siyana. The resistor kunge waya.

Zvino tora bvunzo kunotungamirira kukwanisa kuraramisa magetsi ruchiyerera napakati resistor. We batanidza navo kwachiri achishandisa waya kuti anogona kukunda yamunenge uno. Iva nechokwadi kuti vanoda kuva vakanaka solder majoini.

Panguva iyi mutoro forogo haasi kugadzirira asi. Unobva voltmeter (ammeter kwakabatana munguva ngaatevedzane duku resistor) muna kufanana mutoro. Zvino unofanira kuziva polarity pakati Yatanga Kuongorora, yakafanana polarity zvaisanganisira voltmeter. Uyezve zvakafanira chokubvisa panosangana.

Shure kwaizvozvo zvose, isu kugadzirisa zvose pamusoro refractory, insulating, vanachandagwinyira puranga, izvo zvichagoverwa aine mubato. Yatanga Kuongorora anofanira kuiswa kuti kure pakati pavo akanga akaenzana chinhambwe pakati tins zviteshi.

Mutoro chivhariso haafaniri chokuita undoraira bhatiri. Newewo unogona kuzviita pedo nedzimwe mhosva yacho bhatiri. Kana muitiro yamira yapfuura, zvakakwana fefetedza munharaunda. Zvino vapinze chivhariso zvakabatana bhengi vachichinjana.
