Lesson 4.5 Homework 1. A 100 μF air gap capacitor is charged by a 24-V battery through a 1.2 k resistor. If the area of the capacitor plates is 96 cm 2 , calculate (i) the maximum current into the capacitor plates, (ii) the rate of change of electric field between the plates when the current is maximum, (iii) the magnetic field induced between the plates. 2. In a region of space, the electric field varies with time according to E = 0.05 sin(2000t). Find the maximum displacement current through a 1.0-m 2 are perpendicular to E. 3. A parallel plate air capacitor has circular plates of radius 2.3 cm separated by 1.1 mm. Charge is flowing into the upper plate and out of the lower plate at a rate of 5.0 A. (i) Find the rate of change of electric field between the plates. (ii) Calculate the displacement current between the plates. 4. A capacitor of plate area 0.5 m 2 has a current of 10 A flowing into it. What is the displacement current between the plates? (ii) What is dE/dt between the plates?
