उत्तर
Given: \(R_1=2\,\Omega\)
\(R_2=12\,\Omega\)
\(R_3=6\,\Omega\)
\(R_4=5\,\Omega\)
The 12 Ω and 6 Ω resistors are connected in parallel.
\[ R_p=\frac{12\times6}{12+6}\]
\[=\frac{72}{18}\]
\[ =4\,\Omega \]
This combination is in series with 2 Ω and 5 Ω resistors.
\[ R=2+4+5 \]
\[ {R=11\,\Omega} \]
Equivalent resistance between A and B:
\[ {R=11\,\Omega} \]
