Question

what is the total resistance or equivalent resistance of this circuit?

Explanation:

Step1: Identificar la fórmula para resistores en paralelo

La fórmula para resistores en paralelo es $\frac{1}{R_{eq}}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}$.

Step2: Convertir las resistencias a ohmios

$R_1 = 10\space k\Omega=10000\space\Omega$, $R_2 = 2\space k\Omega = 2000\space\Omega$, $R_3=1\space k\Omega=1000\space\Omega$.

Step3: Sustituir valores en la fórmula

$\frac{1}{R_{eq}}=\frac{1}{10000}+\frac{1}{2000}+\frac{1}{1000}$.
Calculando:
$\frac{1}{R_{eq}}=\frac{1 + 5+10}{10000}=\frac{16}{10000}$.

Step4: Calcular $R_{eq}$

$R_{eq}=\frac{10000}{16}=625\space\Omega$.

Answer:

$625\space\Omega$
