Question

Determine a resistência equivalente na figura abaixo.

Answer 1

$R_1=6\ \Omega,\ R_2=12\ \Omega\ \text{e}\ R_3=6\ \Omega$

$\mathrm{R_2\ e\ R_3\ est\tilde{a}o\ associados\ em\ paralelo.}$

$\Longrightarrow \dfrac{1}{R_{2,3}}=\dfrac{1}{R_2}+\dfrac{1}{R_3}\Longrightarrow\dfrac{1}{R_{2,3}}=\dfrac{1}{12}+\dfrac{1}{6}\ \therefore\ \boxed{R_{2,3}=4\ \Omega}$

$\mathrm{R_1\ e\ R_{2,3}\ est\tilde{a}o\ associados\ em\ s\acute{e}rie.}$

$\Longrightarrow R_{eq}=R_1+R_{2,3}\Longrightarrow R_{eq}=6+4\ \therefore\ \boxed{R_{eq}=10\ \Omega}$
