In Figure, a capacitor with circular plates of radius R = 18.0 cm is connected to a source of emf ξ = ξ m, sin wt, where ξ m = 220 V and w = 130 rad/s. The maximum value of the displacement current is i d = 7.60μA. Neglect fringing of the electric field at the edges of the plates.

(a) What is the maximum value of the current i in the circuit?

(b) What is the maximum value of d Φ E /d t, where ΦE is the electric flux through the region between the plates?

(c) What is the separation d between the plates?

(d) Find the maximum value of the magnitude of E between the plates at a distance r = 11.0 cm from the center.
