Letšoao la amplifier ea multimeter le bolela'ng?

Letšoao la amplifier la multimeter le bohlokoa haholo haeba u batla ho sebelisa multimeter ka nepo. Multimeter ke sesebelisoa sa bohlokoa se ka u thusang maemong a mangata. E ka sebelisoa ho lekola boleng ba lithapo, libeteri tsa teko, le ho fumana hore na ke likarolo life tse etsang hore potoloho ea hau e se ke ea sebetsa hantle. Leha ho le joalo, haeba u sa utloisise matšoao 'ohle a multimeter, e ke ke ea u thusa haholo.

Sepheo se seholo sa letšoao la amplifier ke ho bontša palo ea hona joale e phallang ka potoloho. Sena se ka lekanyetsoa ka ho hokahanya letoto la li-multimeter ka letoto le potoloho le ho lekanya ho theoha ha motlakase ho bona (Molao oa Ohm). Karolo ea tekanyo ena ke li-volts ka ampere (V/A). (1)

Letšoao la amplifier le bolela yuniti ea ampere (A), e lekanyang motlakase o phallang ka har'a potoloho. Tekanyo ena e ka boela ea hlahisoa ka milliamp mA, kiloamps kA kapa megaamp MA ho latela hore na boleng bo boholo kapa bo nyane hakae.

Tlhaloso ea sesebelisoa

Ampere ke tekanyo ea SI ea tekanyo. E lekanya palo ea motlakase o phallang ka ntlha e le 'ngoe motsotsoana o le mong. Ampere e le 'ngoe e lekana le li-electrone tse 6.241 x 1018 tse fetang ntlha e itseng ka motsotsoana o le mong. Ka mantsoe a mang, 1 amp = 6,240,000,000,000,000,000 lielektrone motsotsoana.

Ho hanyetsa le motlakase

Resistance e bolela khanyetso ea phallo ea hona joale potolohong ea motlakase. Ho hanyetsa ho lekanyetsoa ka li-ohms mme ho na le kamano e bonolo pakeng tsa motlakase, hona joale le ho hanyetsa: V = IR. Sena se bolela hore o ka bala hona joale ka li-amps haeba u tseba motlakase le ho hanyetsa. Ka mohlala, haeba ho na le li-volts tse 3 tse nang le khanyetso ea 6 ohms, joale hona joale ke 0.5 amperes (3 e arotsoe ke 6).

Li-amplifier tse ngata

m = milli kapa 10^-3
u = micro kapa 10^-6
n = nano kapa 10^-9
p = pico kapa 10^-12
k = kilogramme e bolela "x 1000". Kahoo, ha u bona letšoao la kA, ho bolela hore boleng ba x ke 1000

Ho na le mokhoa o mong oa ho hlahisa motlakase. Li-unit tse sebelisoang haholo tsa metric system ke ampere, ampere (A), le milliamp (mA).

Foromo: I = Q/t moo:
I= motlakase oa li-amps (A)
Q= tefiso ka coulombs (C)
t= nako ka metsotsoana (s)

Lethathamo le ka tlase le bonts'a bongata ba li-multiples le li-submultiples tsa ampere:

1 MOm = 1,000 Ohm = 1 kOhm
1 mkOm = 1/1,000 Ohm = 0.001 Ohm = 1 mOm
1 nOhm = 1/1,000,000 0 XNUMX Ohm = XNUMX

Dikhutshwafatso

Tse ling tsa likhutsufatso tse tloaelehileng li bua ka maqhubu a motlakase ao u ka kopanang le 'ona. Ke:

mA - milliamp (1/1000 amp)
μA - microampere (1/1000000 ampere)
nA - nanoampere (1/1000000000 ampere)

Mokhoa oa ho sebelisa ammeter?

Li-ammeter li lekanya boholo ba motlakase oa hona joale kapa oa phallo ea motlakase ka li-amps. Li-ammeter li etselitsoe ho hokahana ka letoto le potoloho eo ba e shebileng. Ammeter e fana ka lipalo tse nepahetseng haholo ha potoloho e sebetsa ka botlalo ha e bala.

Li-ammeter li sebelisoa mefuteng e fapaneng ea lisebelisoa tsa motlakase le tsa elektroniki, hangata e le karolo ea lisebelisoa tse rarahaneng joalo ka li-multimeter. Ho tseba hore na ho hlokahala ammeter ea boholo bofe, o hloka ho tseba boholo bo lebelletsoeng hona joale. Ha palo ea li-amps e phahame, terata e hlokahalang bakeng sa ho sebelisoa ka ammeter e ba bophara le ho feta. Lebaka ke hobane maqhubu a phahameng a hlahisa matla a khoheli a ka sitisang ho bala lithapo tse nyane.

Multimeters kopanya mesebetsi e 'maloa ka sesebediswa se le seng, ho akarelletsa le voltmeters le ohmmeters, le ammeters; sena se etsa hore li be tsa bohlokoa haholo bakeng sa lits'ebetso tse fapaneng. Hangata li sebelisoa ke litsebi tsa motlakase, lienjiniere tsa elektronike le bahoebi ba bang.
