Maseketi emagetsi ane ma resistors akafanana uye emukati - matambudziko nemhinduro
1. Zvichibva pamufananidzo uri pazasi, kana sosi yesimba remagetsi (emf) iri 24 Volts, sarudza magetsi emagetsi I.
Zvinozivikanwa:
Kunobva emf = 24 Volt
Kudzivirira kwemukati (r) = 2 Ohms
Zvinopikisa 40 Ohm, 20 Ohm, uye 20 Ohm.
Wante d: Mhepo yemagetsi I
Solution:
Zvipikisi zvakabatana zvakafanana, zvinopikisa zvakaenzana:
1/R = 1/40 + 1/20 + 1/20
1/R = 1/40 + 2/40 + 2/40
1/R = 5/40
R = 40/5
R = 8 Ohm
Vheji yemagetsi:
V = emf – I r
V = 24 – I 2
Mwenje wemagetsi I:
V = IR
24 – Ini 2 = Ini 8
24 = I 8 + I 2
24 = Ini (10)
Ini = 24/10
I = 2.4 Amperes
2. Zvichibva pamufananidzo uri pazasi, kana R 1 = 3 Ω, R 2 = 4 Ω, R 3 = 4 Ω uye magetsi ari 0.5 A. Sarudza voltage yemagetsi.
Zvinozivikanwa:
Mwenje wemagetsi (I) = 0.5 Ampere
Mudziviriri R 1 = 3 Ohm
Mudziviriri R 2 = 4 Ohm
Mudziviriri R 3 = 4 Ohm
Zvinodiwa: Magetsi (V)
Solution:
Verengai kuramba kwakaenzana:
R2 naR3 zvakabatana zvakafanana. Resistor yakaenzana :
1 /R 23 = 1/R 2 + 1/R 3 = 1/4 + 1/4 = 2/4
R 23 = 4/2 = 2 Ohm
R1 naR23 zvakabatana zvakatevedzana. Chinodzivirira chakaenzana :
R = R 1 + R 23 = 3 + 2 = 5 Ohms
Mhepo yemagetsi:
V = IR = (0.5)(5) = 2.5 Volt
