Nice Concept bro

[@shravankumar9660]

Can you explain how is voltage across capacitor 50v .

[@PhysicsNinja]

Shravan Kumar after a long time there is no current (cap is fully charged) which means there is voltage drop across the 1200 ohm resistor. If you pick loop on the left (50v battery, 1200 ohm resistor, and capacitor) you will find that the voltage across capacitor has to be equal to voltage of battery.
