Question

write readings of both voltmeters

Answer 1

$\huge{ \sf \color{lightgrey}{Solution} \color{lightpink}{\ :}}$

Total Resistance, R = ( 12 + 8 ) Ω = 20 Ω

Thus, total Current, I = V/R = 20V/20Ω = 1 A

_______________

Now,

$\boxed{ \red{ \sf v}}$

= $\sf IR_1$

= 1 A × 12 Ω

= ( 1 × 12 ) V

= 12 V

_______________

And,

$\boxed{\sf v}$

= $\sf IR_2$

= 1 A × 8 Ω

= ( 1 × 8 ) V

= 8 V
