Izibonelo ezi-4 zezinkinga ze-Series Resistor

Funda futhi ngezinto zochungechunge lwe-resistor kanye nezibonelo zezinkinga ze-resistor ezihambisanayo.

1. Njengoba u-R ₁ = 2 Ω kanye no-R ₂ = 4 Ω zixhunywe ngochungechunge. Liyini inani le-resistor yokufaka esikhundleni? (Ω = Ohm ).

Ingxoxo

R = R1 ₊ R2 ₌ 2 + 4 = 6 Ω.

Inani lokumelana kokufaka esikhundleni likhulu kunenani lokumelana ngakunye okuxhunywe ochungechungeni.

2. R ₁ = 1 Ω, R ₂ = 2 Ω, R ₃ = 3 Ω. Inani lokumelana kokufaka esikhundleni lingu…..
