Sekit eletriki nwere ihe mgbochi n'otu oge na nguzogide dị n'ime - nsogbu na ngwọta
1. Dabere na eserese dị n'okpuru, ọ bụrụ na isi iyi nke ike electromotive (emf) bụ 24 Volts, chọpụta ọkụ eletrik I.
A maara:
Isi iyi nke emf = 24 Volt
Nguzogide dị n'ime (r) = 2 Ohms
Resistors: 40 Ohm, 20 Ohm, na 20 Ohm.
Achọrọ d: Ọkụ eletrik I
Ngwọta:
Resistors ejikọtara na n'otu oge, resistors nhata:
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
Voltaji njedebe:
V = emf – I r
V = 24 – I 2
Ọkụ eletrik I:
V = IR
24 – I 2 = I 8
24 = M 8 + M 2
24 = I (10)
M = 24/10
I = 2.4 Ampere

2. Dabere na eserese dị n'okpuru, ọ bụrụ na R 1 = 3 Ω, R 2 = 4 Ω, R 3 = 4 Ω na ọkụ eletrik bụ 0.5 A. Chọpụta voltaji eletrik.
A maara:
Ọkụ eletrik (I) = 0.5 Ampere
Nguzogide R 1 = 3 Ohm
Nguzogide R 2 = 4 Ohm
Nguzogide R 3 = 4 Ohm
Achọrọ: Voltaji eletriki (V)
Ngwọta:
Gbakọọ nguzogide nhata:
A na-ejikọ R 2 na R 3 n'otu oge. Ihe mgbochi nhata:
1 /R 23 = 1/R 2 + 1/R 3 = 1/4 + 1/4 = 2/4
R 23 = 4/2 = 2 Ohm
A na-ejikọ R 1 na R 23 n'usoro. Ihe mgbochi nhata:
R = R 1 + R 23 = 3 + 2 = 5 Ohms
Voltaji eletriki:
V = IR = (0.5)(5) = Volt 2.5
