\begin{aligned} & \mathrm{R}_{\mathrm{eq}}=\frac{6}{2}=3 \Omega \\ & \mathrm{I}=\frac{\mathrm{V}}{\mathrm{R}}=\frac{9}{3}=3 \mathrm{~A} \end{aligned}

\begin{aligned} & \mathrm{V}_{\mathrm{A}}+(1.5)(2)-(1.5) 4=\mathrm{V}_{\mathrm{B}} \\ & \mathrm{V}_{\mathrm{A}}-\mathrm{V}_{\mathrm{B}}=3 \mathrm{~V} \end{aligned}
