Sengoloa se mabapi le khoutu ea 'mala oa Resistor
Resistor ke karolo e 'ngoe ea potoloho ea motlakase e sebetsang ho laola palo ea maqhubu a motlakase. Ka kakaretso, ho na le mefuta e 'meli ea li-resistor, e leng li-resistors tsa coil ea terata le li-resistors tsa carbon. Li-resistor tsa roll ea terata hangata li sebelisoa laboratoring, li entsoe ka ho phuthela terata e tšesaane holim'a tube ea insulator. Li-resistor tsa carbon hangata li sebelisoa lipotolohong tsa elektroniki, tse cylindrical, 'me li na le lithapo mahlakoreng ka bobeli. Boleng ba khanyetso ea khanyetso ea carbon bo hlahisoa ka khoutu ea 'mala 'me bo bontšoa holim'a khanyetso.
Boleng ba khanyetso ba resistor bo ka tsejoa ka ho toloka khoutu ea 'mala oa resistor. Ho utloisisa sena, sheba tafole e latelang pele, ebe u ithuta bothata ba mohlala ho fumana boleng ba khanyetso ea resistor.
Bothata ba mohlala oa 1:
Boleng ba khanyetso ea resistor setšoantšong ke …
tharollo:
Mebala e 'meli ea pele e emela linomoro tse peli tsa pele tsa boleng ba khanyetso, 'mala oa boraro o emela matla a leshome a sebelisoang ho atisa, 'me 'mala oa bone o emela mamello ea ho kheloha.
'Mala oa pele = o mofubelu = 2
'Mala oa bobeli = lamunu = 3
'Mala oa boraro = sootho = 101 = 10
'Mala oa bone = khauta = 5%
Boleng ba resistor ke 230 Ω ka ho kheloha ha 5% x 230 Ω = 11.5 Ω. Haeba ho na le phetoho mochesong, khanyetso e fokolang ke 230 11 – 11.5 Ω = 218.5 Ω mme khanyetso e phahameng ke 230 Ω + 11.5 Ω = 241.5 Ω.
Bothata ba mohlala oa 2:
Bohlokoa ba khanyetso ea resistor setšoantšong ke bofe?
tharollo:
'Mala oa pele = sootho = 1
'Mala oa bobeli = o motšo = 0
'Mala oa boraro = putsoa = 10 6 = 1000,000
'Mala oa bone = khauta = 5%
Boleng ba resistor ke 10,000,000 ,000 ka ho kheloha ha 5% x 10,000,000 Ω = 500,000 Ω. Haeba ho na le phetoho mochesong, tšitiso e nyane ke 10,000,000 500 – 500,000 Ω = 9,500,000 Ω mme tšitiso e kholo ke 10,000,000 Ω + 500,000 Ω = 10,500,000 Ω.
