$\mathrm{V}_{\mathrm{A}}-\mathrm{A}_{\mathrm{B}}=1.5 \times 1$
$\mathrm{V}_{\mathrm{A}}-\mathrm{V}_{\mathrm{B}}=1.5$
$\mathrm{V}_{\mathrm{A}}-0=1.5$
$\mathrm{V}_{\mathrm{A}}=1.5 \mathrm{\,V}$
$\mathrm{V}_{\mathrm{B}}-2.5 \times 1+2-\mathrm{V}_{\mathrm{D}}=0$
$\mathrm{V}_{\mathrm{B}}-\mathrm{V}_{\mathrm{D}}-0.5=0$
$0-V_{D}=0.5$
$\mathrm{V}_{\mathrm{D}}=-0.5 \mathrm{\,V}$
