Additional Problems
The figure shows a discharging capacitor. If looked at from the left, in the region between the capacitor's plates there is a magnetic field that is: A) Pointing away from us B) Clockwise C) Pointing towards us D) Uniformly zero E) Counterclockwise
In an RC circuit, the capacitor begins to discharge. During the discharge, in the region or space between the plates of the capacitor, there is a. An electric current but no magnetic field b. A magnetic field but no electric field c. Both electric and magnetic fields d. No fields of any type
A constant current I is supplied for a brief time to charge a parallel plate capacitor. The capacitor has circular plates of radius R with gap d (d << R). Point 1 is at R + d from the wire, and point 2, is at a distance R + d from the center of the capacitor. During the time interval that the constant current I is flowing through the capacitor, the magnetic field at point 2, B2 is: a) B2 > B1 b) B2 = B1 c) 0 < B2 < B1 d) B2 = 0 e) not enough information to tell
A constant current I is supplied for a brief time to charge a parallel plate capacitor. The capacitor has circular plates of radius R with gap d (d << R). Point 1 is at R + d from the wire, and point 2, is at a distance R + d from the center of the capacitor. After the capacitor is charged and the current I goes to zero a) the electric flux and the magnetic field between the plates are both zero. b) the electric flux between the plates is zero and magnetic field between the plates is non-zero. c) the electric flux between the plates is non-zero and the magnetic field between the plates is zero.
