$1\,\Omega$

Vedclass · Answer

(A) $1$. Observe the circuit diagram. The two $2\,\Omega$ resistors on the right are in parallel,giving an equivalent resistance of $R_1 = \frac{2 	imes 2}{2 + 2} = 1\,\Omega$.$2$. This $1\,\Omega$ resistor is in series with the middle $2\,\Omega$ resistor,but due to the symmetry and potential distribution,the circuit simplifies to two $2\,\Omega$ resistors in parallel across $AB$.$3$. As shown in the simplification diagram,the equivalent resistance across $AB$ is $R_{eq} = \frac{2 	imes 2}{2 + 2} = 1\,\Omega$.

Find the equivalent resistance across $AB$ in the given circuit.
