In the above question, after how many time constant will the charge on the capacitor be 10% less than its final charge ?

A

2

B

`2.302`

C

`1/(0.693)`

D

`1/(0.37)`

Text Solution

A parallel plate capacitor with circular plates of radius 1 m has a capacitance of 1 nF. At t = 0, it is connected for charging in series with a resistor R = 1 M Omega across a 2V battery (Fig. 8.3). Calculate the magnetic field at a point P, halfway between the centre and the periphery of the plates, after t = 10^(-3) s . (The charge on the capacitor at time t is q (t) = CV [1 – exp (–t// tau) ], where the time constant tau is equal to CR.)
