FIGURE 8.6
A parallel plate capacitor (Fig. 8.7) made of circular plates each of radius
R = 6.0 cm has a capacitance C = 100 pF. The capacitor is connected to
a 230 V ac supply with a (angular) frequency of 300 rad s?
(a) What is the rms value of the conduction current?
(b) Is the conduction current equal to the displacement current?
(c) Determine the amplitude of B at a point 3.0 cm from the axis
between the plates.
