A 0.5 μF capacitor is connected across a 10 V battery. After a long time, the circuit current and voltage across capacitor will be

0.5 A and 0 V

0 A and 10 V

20 A and 5 V

0.05 A and 5 V

Answer: Option

Explanation:

When the capacitor is fully charged, i = 0 and voltage across capacitor is equal to battery voltage.
