Physics - Current Electricity Question with Solution | TestHub

According to Kirchhoff voltage law

${\mathrm{V}}_{\mathrm{A}}\mathrm{ }–2\mathrm{ }\times \mathrm{ }6-\mathrm{ }12-\mathrm{ }2\mathrm{ }\times \mathrm{ }9+4-\mathrm{ }2\mathrm{ }\times \mathrm{ }5={\mathrm{V}}_{\mathrm{B}}$

$\therefore \mathrm{ }{\mathrm{V}}_{\mathrm{A}}-\mathrm{ }{\mathrm{V}}_{\mathrm{B}}=48\mathrm{ }\mathrm{V}$
