Kukurukurirana

Mavara ekudzivirira resistor anowanzo ratidzwa uchishandisa kodhi yemavara. Mavara maviri ekutanga anomiririra manhamba maviri ekutanga ehukuru hwekudzivirira, ruvara rwechitatu runomiririra simba regumi rinoshandiswa pakuwanda, uye ruvara rwechina runomiririra kutsauka kwekutsungirira.

Ruvara rwekutanga = yero = 4

Ruvara rwechipiri = pepuru = 7

Ruvara rwechitatu = orenji = 10 ³ = 1000

Ruvara rwechina = sirivha = 10%

Saka kukosha kwetransistor i47000 Ohms ± 10% = 47 kiloOhms ± 10%

Mhinduro chaiyo ndeiyi B.

6. Resistor ine mavara akaita sebrown, red, green, gold, saka resistor ine resistor...

A. 1200 kΩ

B. 1200 Ω

C. 120 Ω

D. 12 Ω

Kukurukurirana

Mavara ekudzivirira resistor anowanzo ratidzwa uchishandisa kodhi yemavara. Mavara maviri ekutanga anomiririra manhamba maviri ekutanga ehukuru hwekudzivirira, ruvara rwechitatu runomiririra simba regumi rinoshandiswa pakuwanda, uye ruvara rwechina runomiririra kutsauka kwekutsungirira.

Ruvara rwekutanga = brown = 1

Ruvara rwechipiri = rutsvuku = 2

Ruvara rwechitatu = girini = 10 ⁵ = 100.000

Ruvara rwechina = goridhe = 5%

Saka kukosha kwetransistor i1.200.000 Ohms ± 5% = 1200 kiloOhms ± 5%

Mhinduro chaiyo ndiA.

7. Tarisa mufananidzo we resistor uri pazasi!

Kukosha kwekudzivirira kwe resistor iyi…

A. 270.000 Ω ± 10%

B. 27.000 Ω ± 10%

C. 2.700 Ω ± 10%

D. 270 Ω

Kukurukurirana

Ruvara rwekutanga = rutsvuku = 2

Ruvara rwechipiri = pepuru = 7

Ruvara rwechitatu = yero = 10 ⁴ = 10.000

Ruvara rwechina = sirivha = 10%

Saka kukosha kwetransistor i270.000 Ohms ± 10% = 270 kiloOhms ± 10%

Mhinduro chaiyo ndiA.
