Three resistors of 6 ohms each are connected as shown in the following figure. The equivalent resistance between $X_1$ and $X_2$ is \n\n[Figure needs to be uploaded later]
- A. 2 ohms
- B. 4 ohms
- C. 8 ohms
- D. 12 ohms
Answer: A. 2 ohms
Explanation: [Figure needs to be uploaded later]\nThese three resistances are in parallel, so $\frac{1}{R_{eq}} = \frac{1}{6} + \frac{1}{6} + \frac{1}{6} = \frac{3}{6}$. $R_{eq} = \frac{6}{3} = 2 \Omega$.
