8 Tusaalooyin oo ah Dhibaatooyinka Korontada
1. Dareeraha korontada oo ah 1 Coulomb ayaa dhex mara fiilada koontaroolka muddo 1 ilbiriqsi ah. Cabbirka qulqulka korontada waa…..
Dood
Waa la ogyahay in:
Kharash (Q) = 1 Coulomb
Muddada (t) = 1 ilbiriqsi
La weydiiyay: Koronto koronto
Jawaab:
I = Q / t = 1 / 1 = 1 Coulomb/ilbiriqsi = 1 Ampere
2. Mowjad 2 Amperes ah ayaa dhex marta silig muddo 8 ilbiriqsi ah. Go'aami baaxadda dallacaadda oo dhex marta dhibic iyo tirada elektaroonada ku jira dallacaaddaas!
Dood
Waa la ogyahay in:
Koronto (I) = 1 Amperes
Muddada (t) = 2 ilbiriqsi
Su'aal: dallacaadda (Q) iyo tirada elektaroonada (e)
Jawaab:
Qaacidada hadda korontada:
I = Q/t
Sharaxaadda qaacidada: I = koronto, Q = koronto, t = waqti kala go'an
Kharashka korontada:
Q = I t = (2 Ampere)(8 ilbiriqsi) = 16 Coulombs.
Xawaaraha hal elektarooni waa 1,6 x 10 -19 Coulombs sidaa darteed xawaaraha 16 Coulombs wuxuu leeyahay elektaroono badan sida 16 C / 1,6 x 10 -19 Coulombs = 10 x 10 19 elektaroono.
3. 10 mA = …… Ampere?
Dood
1 Ampere = 1000 milli Ampere
1 milliam Ampere = 1/1000 Ampere
10 milliAmpere = 10/1000 Ampere = 1/100 Ampere = 1/10 2 Ampere = 10 -2 Ampere = 0,01 Ampere
4. Fiiri sawirka!
– Go'aami jihada uu u socdo qulqulka korontada!
– Go'aami jihada dhaqdhaqaaqa elektarooniga ah!
Dood
Korontada korontadu waxay ka dhaqaaqdaa awood sare una gudubtaa awood hoose. Iyada oo ku saleysan jaantuska, jihada hadda korontadu waa mid ka soo horjeedda saacadda.
Jihada dhaqdhaqaaqa elektarooniga waxay ka bilaabataa tiirka taban ilaa tiirka togan. Iyada oo ku saleysan sawirka, waxay u socotaa dhanka saacadda.
5. Koronto koronto oo ah 10 A ayaa dhex marta koontaroole muddo 2 daqiiqo ah. Qadarka korontada ee dhex marta koontaroole waa...
A. 5 Coulombs
B. 12 Coulombs
C. 20 Coulombs
D. 1200 Coulombs
Dood
Waa la ogyahay in:
Koronto (I) = 10 Amperes
Muddada u dhaxaysa (t) = 2 daqiiqo = 2 x 60 ilbiriqsi = 120 ilbiriqsi
Su'aal: Immisa lacag koronto ah ayaa ku socota koontaroolaha?
Jawaab:
Qaacidada xoogga hadda korontada:
I = q/t
Sharaxaad: I = koronto, q = koronto, t = waqti kala go'an
Kharashka korontada:
q = I t = (10)(120) = 1200 Coulombs
Jawaabta saxda ah waa D.
6. Haddii 60 Coulombs oo koronto ah ay dhex marto fiilo koronto ah 5 daqiiqo gudahood, markaas korontada waa...
A. 0,2 Amperes
B. 0,5 Ampere
C. 3 Ampere
D. 6 Ampere
Dood
Waa la ogyahay in:
Muddada (t) = 5 daqiiqo = 5 x 60 ilbiriqsi = 300 ilbiriqsi
Dakhli koronto (Q) = 60 Coulombs
Su'aal: Xoogga hadda korontada (I)
Jawaab:
Xoogga hadda korontada:
I = Q/t
I = 60/300
I = 0,2 Coulomb/ilbiriqsi
I = 0,2 Amperes
Coulomb/second waxaa sidoo kale loo yaqaan Ampere.
Jawaabta saxda ah waa A.
7. Cutubka SI ee hadda korontada ku shaqeeya waa…
A. ampere
B. volt
C. coulomb
D. ohm
Dood
Nidaamka Caalamiga ah ee Cutubyada ee tirada aasaasiga ah ee korontada waa Ampere.
Jawaabta saxda ah waa A.
8. Korontada uu soo saaro dynamo waxaa lagu sawiri karaa garaafka...
Dood
Sharaxaadda garaafka: I = koronto koronto, t = waqti kala-goyn
Dynamo wuxuu soo saaraa koronto toos ah (DC), halka matoor koronto uu soo saaro koronto beddel ah (AC). Garaafka hadda tooska ah waxaa lagu muujiyay jawaabta D, halka garaafka hadda beddelna lagu muujiyay jawaabta B.
Jawaabta saxda ah waa D.
