The circuit sketched below contains a switch, an ideal battery with an emf of 13.5 volts, a 19 MΩΩ resistor, and an air-filled capacitor. The capacitor has parallel circular plates of radius 5.2 cm separated by 1 mm. At time t=0 the switch is closed to begin charging the capacitor. You may assume that the electric field between the plates is uniform.
(A) Calculate the capacitance of the capacitor. (Think back to
Ch 8!) pF
(B) What is the time constant for this RC circuit? (DC circuits: Ch
10!) μμs
(C) How much current is flowing in the circuit when t=40 μμs? (Ch
10 again! Think about the maximum current and then how will the
current change with time?) μμA
(D) What is the total displacement current flowing through the
capacitor when t=40 μμs? (Don't overthink this
one!) μμA
(E) What is the magnitude of the induced magnetic field between the
capacitor plates at a radial distance 3.12 cm from the center when
t=40 μμs? (How much of the displacement current is relevant for
3.12 cm from the center?) pT
