Question

Resistência equivalente

Answer 1

Resistores em Paralelo:
$\boxed{\frac{1}{Req}=\frac{1}{R1}+\frac{1}{R2}+\frac{1}{R3}}$
$\boxed{\frac{1}{Req}=\frac{1}{4}+\frac{1}{6}+\frac{1}{12}}$
$\boxed{\frac{1}{Req}=\frac{3+2+1}{12}}$
$\boxed{\frac{1}{Req}=\frac{6}{12}}$
$\boxed{6*Req=12}$
$\boxed{Req=\frac{12}{6}}$
$\boxed{\boxed{Resposta:Req=2-Ohm}}$
