Matla a motlakase ho mokhanni oa bolo - mathata le litharollo
1. Mokhanni oa bolo e se nang letho oa 4-μC o na le radius ea 8-cm. Fumana matla a motlakase holim'a bolo. (k = 9.10 9 Nm 2 .C -2 )
Tse tsejoang:
The tefiso ea motlakase (Q) = 4 μC = 4 x 10-6 C 
Radius ea bolo (r) = 8 cm = 8 x 10 -2 m
Sephetho sa Coulomb (k) = 9.10 9 Nm 2 .C -2
Ho batloa: Matla a motlakase holim'a bolo (V)
Lipotoloho tsa capacitor tsa letoto le tse bapileng - mathata le litharollo
1. Litefiso tsohle tsa capacitor tse ka tlase ke life (1 μF = 10 -6 F)
Tse tsejoang:
Motlakase oa 1 (C1) = 3 μF
Motlakase 2 (C 2 ) = 3 μF
Motlakase 3 (C 3 ) = 3 μF
Motlakase 4 (C 4 ) = 2 μF
Motlakase 5 (C 5 ) = 3 μF
Motlakase (V) = 3 Volt
Ho kenya matla a khoheli - mathata le litharollo
1. Mabaka a latelang a susumetsa tlhahiso ea makenete terata ea conductor.
(1) phallo ea motlakase ka har'a terata
(2) tumello
(3) ho teteana ha terata
(4) sebaka sa ntlha ho tloha terata
Ke lipolelo life tse nepahetseng
Khopolo-taba e ikhethang ea kamano - mathata le litharollo
1. Ntho e bolelele ba yona e leng 60 m e tsamaya ka lebelo la 0.6 c (c = lebelo la lesedi). Ho ya ka moshebelli ya sa sisinyeheng, bolelele ba ntho eo ke bofe?
Tse tsejoang:
Bolelele bo nepahetseng (Lo ) = limithara tse 60
Lebelo la ntho (v) = 0.6 c
Ho batloa: Ho khutsufala ha bolelele (L)
Maqhubu a emang - mathata le litharollo
1. Thapo ea limithara tse 3 e tlameletsoe pheletsong e 'ngoe 'me pheletso e 'ngoe e hokahantsoe le vibrator. Ha vibrator e thothometsoa, khoele e etsa leqhubu le sa sisinyeheng , joalo ka ha ho bontšitsoe setšoantšong se ka tlase.
Fumana sebaka sa antinode ea bohlano ho tloha pheletsong e tsitsitseng.
Tharollo:
Sebaka se pakeng tsa li-node tse peli = limithara tse 3 / 5 = limithara tse 3/5.
Sebaka se pakeng tsa leqhubu la pele le pheletso e tsitsitseng = 3/5 metres
Matla a makenete pakeng tsa lithapo tse peli tse bapileng - mathata le litharollo
1. Dikhonthara tse pedi tse bapileng tse jereng maqhubu a I 1 le I 2 , jwalo ka ha ho bontshitswe setshwantshong se ka tlase. Boholo le tataiso ya matla a makenete a fumanwang ke dikhonthara ka bobedi ke efe ? (μ o = 4π. 10 -7 Wb.A -1 .m -1 )
Tse tsejoang:
The motlakase 1 (I1) = 3 Ampere
Motlakase oa motlakase 2 (I 2 ) = 5 Ampere
Ho kenella ha sebaka se lokolohileng (µo ) = 4π x 10 -7 wb A -1 m -1
Sebaka pakeng tsa batsamaisi ka bobeli (L) = 5 cm = 5 x 10 -2 metres
Melao ea Kirchhoff - mathata le litharollo
1. Motlakase oa terminal oa betri potolohong e ka tlase ke ofe?
tharollo
emf = matla a motlakase = phapang e ka bang teng pakeng tsa li-terminal ha ho se na hajwale phallo ho ea potolohong e kantle.
Motlakase oa terminal (V) = phapang e ka bang teng lipakeng tsa li-terminal ha motlakase o phalla ho tsoa betring.
Haeba ho se na motlakase o huloang betring, motlakase oa terminal o lekana le emf.
Tse tsejoang:
Motsamao o otlolohileng - mathata le litharollo
1. Bolo A e lahlela holimo ka lebelo la 10 m/s. Motsotsoana o le mong hamorao, ho tloha boemong bo tšoanang, Bolo B e lahleloa holimo ka lebelo le tšoanang, ka lebelo la 25 m/s. Bolo B e bophahamo bo bokae ha e kopana le bolo A?
Tharollo:
Ha ho rarolloa bothata ba motsamao o otlolohileng , bongata ba vekthara bo shebaneng le hodimo bo fuwa letshwao le letle, bongata ba vekthara bo shebaneng le hodimo bo fuwa letshwao le lebe.
Matla a motlakase a sa fetoheng – mathata le ditharollo
1. Haeba matla a motlakase a sa fetoheng a 144 N, sebaka se pakeng tsa litefiso ka bobeli ke sefe … (1 μC = 10 -6 C le k = 9.10 9 Nm 2 .C -2 )
Tse tsejoang:
