$\large\underline{\boxed{\bold\blue{Answer}}}$

$\large\underline{\boxed{\bold\purple{Given}}}$

$\large\pink{R = 8 \: ohm}$

$\large\pink{I = 10A}$

$\large\pink{V = ?}$

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\large\green{Ohm's law = V = I×R \: or \:I = \dfrac{V}{R} }$

$\purple{:\leadsto} \large\orange{V = 8×10}$

$\large\purple{:\leadsto}\orange{ V = 80 \: volt}$
