Questions
A capacitor is connected to a 12 V battery through a resistance of 10Ω . It is found that the potential difference across the capacitor rises to 4.0 V in 1µS . Find the capacitance of the capacitor.
(Given )
detailed solution
Correct option is A
The charge on the capacitor during charging is given by .
Hence, the potential difference across the capacitor is
Here at t = 1µs , the potential difference is 4 V whereas the steady state potential difference is .Or, Or,
