In the given circuit, the equivalent resistance between the terminal A and B is __________ Ω. Numerical answer type. Work it out, then open the answer.

Answer: 10. The thick vertical wire joins the two right-hand dots, so the 4 Ω loop is shorted and the node after the top 2 Ω is at the bottom-rail potential; the second vertical 2 Ω is shorted too. From the node after 3 Ω to the bottom rail: 2 Ω (vertical) ∥ 2 Ω (top) = 1 Ω. RAB = 3 + 1 + 6 = 10 Ω

Combination of Resistors

In the given circuit, the equivalent resistance between the terminal A and B is __________ $\Omega$ .

Numerical answer type. Work it out, then open the answer.

Show answer and solution

Answer: 10

The thick vertical wire joins the two right-hand dots, so the $4\ \Omega$ loop is shorted and the node after the top $2\ \Omega$ is at the bottom-rail potential; the second vertical $2\ \Omega$ is shorted too.
From the node after $3\ \Omega$ to the bottom rail: $2\ \Omega$ (vertical) $\parallel$ $2\ \Omega$ (top) $= 1\ \Omega$ .
$R_{AB} = 3 + 1 + 6 = 10\ \Omega$
