Question

For setup shown in diagram, find $V_A-V_B$

• A. 13 V
• B. 16 V
• C. 8 V
• D. 12 V

Answer 1

The correct option is A 13 V

$V_A-\stackrel{\underset{}{Battery}}{4}-\underset{Resistance}{\underset{}{8}}+\stackrel{\underset{}{Battery}}{8}-\underset{Resistance}{\underset{}{12}}+\stackrel{\underset{}{Capacitor}}{3}=V_B{V}_A-V_B=13V$
