A Capacitor Is Hooked Up to a Resistor and an AC

question 30

Multiple Choice

A capacitor is hooked up to a resistor and an AC voltage source as shown in the figure. The output of the source is given by V(t) = V₀ sin ωt. The plates of the capacitor are disks of radius R. Point P is directly between the two plates, equidistant from them and a distance R/2 from the center axis. At point P

• A) there is no magnetic field because there is no charge moving between the plates.
• B) there is a constant magnetic field.
• C) there is a time-varying magnetic field.
