The given electrical network is equivalent to:

1. If two NOR gates act as NOT gates (inputs shorted) for $A$ and $B$, their outputs are $\bar{A}$ and $\bar{B}$.2. These feed into a third NOR gate: Output $Y=\overline{\bar{A}+\bar{B}}=\overline{\stackrel{ˉ}{A}}\cdot \overline{\stackrel{ˉ}{B}}=A\cdot B$.This is an AND gate.Note: If the diagram shows a different configuration (like two inputs to one NOR and its output split), the result varies. Based on NEET 2017 network: NOR(NOR(A,A), NOR(B,B)) is AND.
