At time t = 0, a battery of 10 V is connected across points A abd B In the given circuit. If the capacitors hace no charge initially, at what time (in seconds) does the voltage across them becomes 4 volt?

Text Solution

Verified by Experts

The correct Answer is:
2

`4=10(1-e^(-t//4))`
`therefore t=2 sec` Here, `q=(epsilon_0AV)/(d)`
