Lisebelisoa tsa Resistor tsa Letoto la Litaba
Haeba di-resistor di hokahantswe jwalo ka ha ho bontshitswe setshwantshong se ka ho le letona, di hokahantswe ka tatellano. Di-resistor tse boletsweng e ka ba dikarolo tsa resistor, mabone, kapa disebediswa tse ding tsa ho thibela motlakase.
Tefiso ea motlakase (Q) e lula e le hore tefiso ea motlakase e tsamaeang ka khanyetso 1 (R 1 ) = tefiso ea motlakase e tsamaeang ka khanyetso 2 (R 2 ) = tefiso ea motlakase e tsamaeang ka khanyetso 3 (R 3 ). Motlakase oa motlakase (I) ke tefiso ea motlakase e phallang nakong e itseng ea nako (I = Q/t), ka hona motlakase o fetang ka khanyetso 1 (I 1 ) = motlakase o fetang ka khanyetso 2 (I 2 ) = motlakase o fetang ka khanyetso 3 (I 3 ). Ka lipalo, motlakase oohle (I) = I 1 = I 2 = I 3.
Ka lehlakoreng le leng, motlakase (V) oa fokotseha ha tjhaja ea motlakase e feta khanyetsong e 'ngoe le e 'ngoe. Motlakase oa motlakase, o boetse o bitsoa phapang ea matla a motlakase, ke matla a matla a motlakase ka yuniti ea tjhaja ea motlakase. Motlakase oa motlakase oa fokotseha hobane matla a motlakase a sebelisoa khanyetsong e 'ngoe le e 'ngoe ea motlakase. Kahoo motlakase oohle oa motlakase (V) o lekana le kakaretso ea motlakase khanyetsong e 'ngoe le e 'ngoe. Ka lipalo, motlakase oohle oa motlakase (V) = V 1 + V 2 + V 3 . V = IR e le hore equation ea motlakase oohle oa motlakase V = IR 1 + IR 2 + IR 3 . Motlakase o phallang khanyetsong e 'ngoe le e 'ngoe o ts'oana kahoo equation ena e fetoha ho V = I (R 1 + R 2 + R 3 ).
Ho latela equation e kaholimo, ho fihletsoe qeto ea hore khanyetso eohle ea motlakase (R) kapa khanyetso e nkelang sebaka ea khanyetso ea motlakase e hoketsoeng letotong e lekana le kakaretso ea khanyetso e 'ngoe le e 'ngoe ea motlakase, ka lipalo R = R 1 + R 2 + R 3 . Haeba ho na le li-resistor tse peli feela tse hoketsoeng letotong, boleng ba resistor e nkelang sebaka (R) = R 1 + R 2 . Haeba ho na le li-resistor tse 'ne tse hoketsoeng letotong, boleng ba resistor e nkelang sebaka (R) = R 1 + R 2 + R 3 + R 4 . Ka mokhoa o ts'oanang, haeba ho na le li-resistor tse hlano kapa tse fetang tse hlano tse hoketsoeng letotong.
Mohlala oa bothata ba ho hanyetsa letoto:
1. Ha ho fanoe ka R 1 = 2 Ω, R 2 = 3 Ω le R 3 = 4 Ω. Li-resistor tse tharo li hokahane ka letoto. Boleng ba resistor e nkelang sebaka ke bofe? (Ω = Ohm).
Puisano
R = R 1 + R 2 + R 3 = 2 + 3 + 4 = 9 Ω.
Sephetho sena se bontša hore boleng ba khanyetso e nkeloang sebaka bo boholo ho feta boleng ba khanyetso ba khanyetso ka 'ngoe e hokahantsoeng ka letoto.
2. Li-resistor tse peli R 1 = 50 Ω le R 2 = 50 Ω li hokahane ka tatellano 'me li hokahantsoe le betri ea 12 Volt. Fumana (a) khanyetso e lekanang (b) motlakase o fetang ka har'a resistor ka 'ngoe.
Puisano
(a) R = R 1 + R 2 = 50 Ω + 50 Ω = 100 Ω.
(b) I = V / R = 12 Volts / 100 Ω = 0,12 Ampere
