# The equivalent resistance

Question:

The equivalent resistance of the given circuit between the terminals $\mathrm{A}$ and $\mathrm{B}$ is :

1. $0 \Omega$

2. $3 \Omega$

3. $\frac{9}{2} \Omega$

4. $1 \Omega$

Correct Option: , 4

Solution:

$R_{e q}=\frac{3 \times 3 / 2}{3+3 / 2}=\frac{9 / 2}{9 / 2}=1 \Omega$
