A capacitor consists of two circular parallel plates of radius r=150 mm, separated by a distance d=20 mm. The initial magnitude of the charge on the capacitor is q=9.0 x 10^-8 C, and after discharge is initiated it discharges via a steady current I=2.5 mA. (a) What is the power that crosses the closed cylindrical surface surrounding the space between the plates 2.0 x 10^-5 seconds after discharge begins? (b) What is this power at t=2.0 μs?
A parallel-plate capacitor consists of two plates, each with an area of 36 cm2, separated by 9.0 mm. The charge on the capacitor is 2.1 nC. An electron is released from rest next to the negative plate. How long does it take for the electron to reach the positive plate? Exoress your answer in ns.

A parallel plate capacitor is formed with two plates separated by 5.00 mm as shown in Figure 1. Each plate is a 10.0 cm X 10.0 cm square. We do not know the charge on the plates. An electron beam is shot in from one edge of the capacitor. It enters the capacitor very close (call it 0 mm) from the top plate and travelling parallel to the plates. The electrons in the beam are moving at 1.50 × 107...
