Mehlala e 8 ea Mathata a Motlakase
1. Tefiso ea motlakase ea Coulomb e le 1 e feta ka har'a terata ea conductor ka motsotsoana o le 1. Boholo ba motlakase ke…..
Puisano
Hoa tsebahala hore:
Tefiso (Q) = 1 Coulomb
Nako ea ho arohana (t) = metsotsoana e 1
E botsitsoe: Motlakase oa motlakase
Karabo:
Ke = Q / t = 1 / 1 = 1 Coulomb/motsotswana = 1 Ampere
2. Motlakase oa li-Ampere tse 2 o phalla ka har'a terata metsotsoana e 8. Fumana boholo ba tjhaja e fetang ntlheng le palo ea lielektrone tse tjhajang eo!
Puisano
Hoa tsebahala hore:
Motlakase oa motlakase (I) = 1 Ampere
Nako ea ho arohana (t) = metsotsoana e 2
Potso: tjhaja (Q) le palo ya dielektrone (e)
Karabo:
Foromo ea motlakase oa hona joale:
Ke = Q/t
Tlhaloso ea foromo: I = motlakase oa motlakase, Q = tjhaja ea motlakase, t = nako ea ho arohana
Tefiso ea motlakase:
Q = I t = (2 Ampere)(metsotsoana e 8) = 16 Coulombs.
Tefiso ea elektrone e le 'ngoe ke 1,6 x 10 -19 Coulombs kahoo tefiso ea Coulombs tse 16 e na le lielektrone tse ngata tse ka bang 16 C / 1,6 x 10 -19 Coulombs = 10 x 10 19 lielektrone.
3. 10 mA = …… Ampere?
Puisano
Ampere e le 1 = 1000 milliampere
1 milliampere = 1/1000 Ampere
10 milliAmpere = 10/1000 Ampere = 1/100 Ampere = 1/10 2 Ampere = 10 -2 Ampere = 0,01 Ampere
4. Sheba setšoantšo!
– Fumana tsela eo motlakase o tsamayang ka yona!
– Fumana tataiso ea motsamao oa lielektrone!
Puisano
Motlakase o tloha ho bokgoni bo phahameng ho ya ho bokgoni bo tlase. Ho itshetlehile ka setshwantsho, tataiso ya motlakase e fapana le watjhe.
Tsela eo motsamao oa lielektrone o tsamaeang ka eona e tloha palong e mpe ho ea palong e ntle. Ho latela setšoantšo, e tsamaea ka lehlakoreng la oache.
5. Motlakase oa 10 A o phalla ka har'a kondakta metsotso e 2. Palo ea tjhaja ea motlakase e phallang ka har'a kondakta ke...
A. 5 Coulombs
B. 12 Coulombs
C. 20 Coulombs
D. 1200 Coulombs
Puisano
Hoa tsebahala hore:
Motlakase oa motlakase (I) = 10 Ampere
Nako e sa fellang (t) = metsotso e 2 = metsotsoana e 2 x 60 = metsotsoana e 120
Potso: Ke tjhaja e kae ya motlakase e phallang ka hara conductor?
Karabo:
Foromo ea matla a motlakase:
Ke = q/t
Tlhaloso: I = motlakase, q = tjhaja ya motlakase, t = nako e sa fellang
Tefiso ea motlakase:
q = I t = (10)(120) = 1200 Coulombs
Karabo e nepahetseng ke D.
6. Haeba di-Coulomb tse 60 tsa tjhaja ya motlakase di phalla ka hara terata e tsamaisang motlakase ka metsotso e 5, jwale motlakase o...
A. 0,2 Li-ampere
B. 0,5 Ampere
C. 3 Ampere
D. 6 Ampere
Puisano
Hoa tsebahala hore:
Nako e sa fellang (t) = metsotso e 5 = metsotsoana e 5 x 60 = metsotsoana e 300
Tefiso ea motlakase (Q) = 60 Coulombs
Potso: Matla a motlakase (I)
Karabo:
Matla a motlakase:
Ke = Q/t
Ke = 60 / 300
I = 0,2 Coulomb/motsotsoana
I = 0,2 Ampere
Coulomb/second e boetse e bitsoa Ampere.
Karabo e nepahetseng ke A.
7. Yuniti ea SI ea motlakase ke…
A. ampere
B. volt
C. coulomb
D. ohm
Puisano
Sistimi ea Machaba ea Liyuniti bakeng sa bongata ba motheo ba motlakase ke Ampere.
Karabo e nepahetseng ke A.
8. Motlakase o hlahisoang ke dynamo o ka bontšoa kerafong...
Puisano
Tlhaloso ea kerafo: I = motlakase, t = nako e sa fellang
Dynamo e hlahisa motlakase o tobileng (DC), ha jenereithara ea motlakase e hlahisa motlakase o fetohang (AC). Kerafo ea motlakase o tobileng e bontšitsoe karabong ea D, ha kerafo ea motlakase o fetohang e bontšitsoe karabong ea B.
Karabo e nepahetseng ke D.
