Dear Student, 
Please find below the solution to the asked query: 
$$\begin{gathered} \mathrm{Note}: \\ \mathrm{In} \mathrm{the} \mathrm{figure}, \mathrm{it} \mathrm{is} \mathrm{not} \mathrm{clearly} \mathrm{mentioned} \mathrm{that} \mathrm{where} 2 \mathrm{A} \mathrm{current} \\ \mathrm{flows}. \mathrm{So}, \mathrm{I} \mathrm{am} \mathrm{assuming} \mathrm{that} 2 \mathrm{A} \mathrm{current} \mathrm{is} \mathrm{flowing} \mathrm{thorugh} \mathrm{each} \\ 2 \mathrm{A} \mathrm{resistor}. \\ \mathrm{Total} \mathrm{current} \mathrm{through} 8 \mathrm{ohm} \mathrm{resistor}, \mathrm{I} = 2 + 2 = 4 \mathrm{A} \\ \mathrm{Voltage} \mathrm{across} 8 \mathrm{ohm} \mathrm{resistor}: \\ \mathrm{V} = \mathrm{I} \mathrm{R} \\ = 4 * 8 \\ \mathbf{=}\mathbf{ }\mathbf{32}\mathbf{ }\mathbf{V} \end{gathered}$$
