The resultant resistance between $\mathrm{A}$ and $\mathrm{B}$ in the given figure is
The resultant resistance between $\mathrm{A}$ and $\mathrm{B}$ in the given figure is
- $1 \Omega$
- $2 \Omega$
- $3 \Omega$
- $6 \Omega$
Solution
Apply the Wheatstone bridge
$
\begin{aligned}
& \frac{\mathrm{R}_{\mathrm{AB}}}{\mathrm{R}_{\mathrm{BC}}}=\frac{\mathrm{R}_{\mathrm{AD}}}{\mathrm{R}_{\mathrm{DC}}}=\frac{3}{3}=\frac{3}{3} \\
& \mathrm{R}_{\mathrm{AB}}=\frac{6 \times 6}{6+6}=3 \Omega
\end{aligned}
