Question

In the circuit below $C_{1}=20\, \mu F , C_{2}=40 \,\mu F$ and $C_{3}=50 \,\mu F$. If no capacitor can sustain more than $50 V$, then maximum potential difference between $X$ and $Y$ is

• A. 95 V
• B. 75 V
• C. 150 V
• D. 65 V

Answer 1

Answer: (A)

$q_{\max }=1000\, \mu C , 2000 \,\mu C , 2500 \,\mu C$
$q=1000 \,\mu C , 1000\, \mu C , 1000\, \mu C$
$V=50 \,V , 25\, V , 20\, V$
$V_{\text {net }}=50+20+25$
$V_{\text {net }}=95 \,V$
