Chinyorwa nezvekodhi yemavara yeResistor
Resistor chimwe chezvinhu zvedunhu remagetsi chinoshanda kudzora huwandu hwemagetsi. Kazhinji, kune mhando mbiri dzeresistor, dzinoti wire coil resistors uye carbon resistors. Wire roll resistors dzinowanzo shandiswa murabhoritari, dzinogadzirwa nekuputira waya yakapfava pamusoro pechubhu yeinsulator. Carbon resistors dzinowanzo shandiswa muma electronic circuits, cylindrical, uye dzine waya kumativi ese. Kukosha kwe carbon resistor resistor kunoratidzwa mu color code uye kunoratidzwa pamusoro pe resistor.
Kukosha kweresistor kunogona kuzivikanwa nekududzira kodhi yeruvara rweresistor. Kuti unzwisise izvi, tanga watarisa tafura inotevera, wobva wadzidza muenzaniso wedambudziko kuti uone kukosha kweresistor resistor.
Dambudziko remuenzaniso 1:
Kukosha kwekudzivirira kwemuchina pamufananidzo uyu ndekwekuti …
Solution:
Mavara maviri ekutanga anomiririra nhamba mbiri dzekutanga dze resistance value, ruvara rwechitatu runomiririra simba regumi rinoshandiswa kuwanza, uye ruvara rwechina runomiririra tolerance of deviation.
Ruvara rwekutanga = rutsvuku = 2
Ruvara rwechipiri = orenji = 3
Ruvara rwechitatu = brown = 101 = 10
Ruvara rwechina = goridhe = 5%
Kukosha kwe resistor i230 Ω ine kutsauka kwe5% x 230 Ω = 11.5 Ω. Kana paine shanduko mukupisa, resistance shoma i230 11 – 11.5 Ω = 218.5 Ω uye resistance yepamusoro i230 Ω + 11.5 Ω = 241.5 Ω.
Dambudziko remuenzaniso 2:
Chii chinonzi resistor resistance mumufananidzo?
Solution:
Ruvara rwekutanga = brown = 1
Ruvara rwechipiri = dema = 0
Ruvara rwechitatu = bhuruu = 106 = 1000,000
Ruvara rwechina = goridhe = 5%
Kukosha kwe resistor i10,000,000 ,000 ine kutsauka kwe5% x 10,000,000 Ω = 500,000 Ω. Kana paine shanduko mukupisa, chipingamupinyi chidiki i10,000,000 500 – 500,000 Ω = 9,500,000 Ω uye chipingamupinyi chikuru i10,000,000 Ω + 500,000 Ω = 10,500,000 Ω.
