Question

Rezistenta echivalenta a 3 consumatori idetici legati in serie este R=18ohmi. Rzistenta echivalenta a celor 3 consumatori legati in paralel are valoarea ?

Answer 1

Rs= n x R => R= Rs/n=> R=18/3=6; Rp=R/n=> Rp= 6/3=> Rp=2 ohmi

Answer 2

Răspuns:

Explicație:

Rs=R+R+R=18Ω ->>>3R=18->>R=3Ω

$\frac{1}{Rp}$=$\frac{1}{R}$ + $\frac{1}{R}$+$\frac{1}{R}$= $\frac{3}{R}$

Rp=$\frac{R}{3}$= $\frac{6}{3}$

Rp=2Ω
