To solve this problem, we need to analyze the given logic circuit.$\\$The circuit consists of:$\\$• An OR gate with inputs $A$ and $B. \\$• A NOT gate (inverter) following the OR gate.$\\$Let's break down the circuit step-by-step:$\\$1. The OR gate outputs $A + B. \\$ (The OR operation results in a high output if either $A$ or $B$ is high.)$\\$2. The output of the OR gate is fed into a NOT gate.$\\$ The NOT gate inverts the input, so the output becomes $\overline{A + B}. \\$The final output of the circuit is $\overline{A + B},$ which is the logical NOR operation.$\\$Therefore, the given electrical network is equivalent to a NOR gate.$\\$This corresponds to Option 2.
