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.
Ho fapana le moo motlakase oa motlakase (V) ea fokotseha ha tjhaja ea motlakase e feta khanyetsong e 'ngoe le e 'ngoe. Motlakase oa motlakase, oo hape o bitsoang phapang ea matla a motlakase, ke matla a motlakase ka yuniti ea tjhaja ea motlakase. 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. Ho ea ka lipalo, motlakase oohle oa motlakase (V) = V1 +V2 +V3. V = IR kahoo equation yohle ya motlakase wa motlakase ke V = IR1 + IR2 + IR3Motlakase o phallang ka har'a resistor ka 'ngoe o na le boleng bo tšoanang kahoo equation ena e fetoha ho V = I (R)1 + R2 + R3).
Ho latela equation e kaholimo, ho ka fihlelletsoa qeto ea hore khanyetso eohle ea motlakase (R) kapa khanyetso e lekanang ea khanyetso ea motlakase e hokahantsoeng ka tatellano e tšoana le kakaretso ea khanyetso e 'ngoe le e 'ngoe ea motlakase, ka lipalo R = R1 + R2 + R3Haeba ho na le li-resistor tse peli feela tse hokahaneng ka tatellano, joale boleng ba resistor e nkeloang sebaka (R) = R1 + R2Haeba ho na le li-resistor tse 'ne tse hokahaneng ka tatellano, boleng ba resistor e nkeloang sebaka (R) = R1 + R2 + R3 + R4Ka ho tšoanang, haeba ho na le li-resistor tse hlano kapa ho feta tse hokahaneng ka tatellano.
Mohlala oa bothata ba ho hanyetsa letoto:
1. E fanoe ka R1 = 2 Ω, R2 = 3 Ω le R3 = 4 Ω. Li-resistor tse tharo li hokahane ka tatellano. Boleng ba resistor e nkelang sebaka ke bofe? (Ω = Ohm).
Puisano
R = R1 + R2 + R3 = 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. Lihanyetsi tse peli R1 = 50 Ω le R2 = 50 Ω e hokahantsoe ka tatellano mme e 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
