Question

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? 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/?)], where the time constant ? is equal to CR.) OP = 0.5m 1M? 2V
