Question

Qual o resistor equivalente da associação representada no esquema da figura?



11 Ω
12 Ω
4 Ω
2 Ω
6 Ω​

Answer 1

$\frac{1}{Req}=\frac{1}{10} +\frac{1}{10} +\frac{1}{20}\\\\\frac{1}{Req}=\frac{2}{20} +\frac{2}{20} +\frac{1}{20}\\\\\frac{1}{Req}=\frac{5}{20}\\\\Req=\frac{20}{5}$

Req = 4 Ω

Answer 2

Resposta:

Req= 4 ohms

Explicação:

Req1= (10×10)÷(10+10) Req1= 100÷20 Req1= 5 ohms

Req= (5×20)÷(5+20) Req= 100÷25 Req= 4 ohms
