Physics

A 100 pF capacitor has circular plates of 10.0 cm radius thatare 5.0 mm apart and have air beteween them. The capacitor ischarged by connecting it to a 12.0 V battery through a 1.0 ohmsresistor.

a) Determine the current through the plates at t = 0 (when thebattery is connected)

b) Determine the current through the plates at t = 60s?

c) Determine the rate at which the electric field between theplates changes at t= 0 and t = 60s

d) Determine the magnetic field between the plates at t = 0 andat t = 60s


Don't really care about the answers as much, but more about whatformulas are being used.

Thanks!
