Ihe atụ anọ nke nsogbu ndị na-emegiderịta onwe ha

Mụtakwuo ihe gbasara resistors ndị yiri ya na ihe atụ nke nsogbu resistors usoro , ihe atụ nke nsogbu iguzogide eletriki.

1. Ebe ọ bụ na R ₁ = 2 Ω na R ₂ = 4 Ω jikọtara n'otu oge. Gịnị bụ uru nke resistor nnọchi? (Ω = Ohm).

Mkparịta ụka

1/R = 1/R ₁ + 1/R ₂ = 1/2 + 1/4 = 2/4 + 1/4 = 3/4

R = 4/3 Ω

Uru nke nguzogide nnọchi dị ukwuu karịa uru nke nguzogide ọ bụla ejikọtara na usoro.

Ihe atụ anọ nke nsogbu ndị na-eguzogide usoro

Mụtakwa ihe ndị metụtara usoro ihe mgbochi na ihe atụ nke nsogbu ndị metụtara nsogbu mgbochi.

1. Ebe ọ bụ na R ₁ = 2 Ω na R ₂ = 4 Ω jikọtara n'usoro. Gịnị bụ uru nke resistor nnọchi? (Ω = Ohm).

Mkparịta ụka

R = R ₁ + R ₂ = 2 + 4 = 6 Ω.

Uru nke nguzogide nnọchi dị ukwuu karịa uru nke nguzogide ọ bụla ejikọtara na usoro.
