Suppose you have a capacitor with circular plates and area A = 100 cm2. The capacitance is 30 pF %3D and the gap between the plates is filled with air. The capacitor is charged with a battery with V = 7OV through a resistor with 22. Suppose also that the circuit is open with a switch and at the moment you close the switch, current starts flowing in the circuit. At the moment you close the switch, calculate: a) the current into the plates; b) the rate of change of the electric field; c) determine the magnetic field induced between the plates. NB you can assume the field E to be uniform between the plates at any instant and zero beyond the edge of the plates. Also assume, because of symmetry, the lined of the field to be circular on the plates.

Question
Suppose you have a capacitor with circular plates and area A = 100 cm². The capacitance is 30 pF and the gap between the plates is filled with air. The capacitor is charged with a battery with V = 70V through a resistor with 22. %3D Suppose also that the circuit is open with a switch and at the moment you close the switch, current starts flowing in the circuit. At the moment you close the switch, calculate: a) the current into the plates; b) the rate of change of the electric field; c) determine the magnetic field induced etween the plates. NB you can assume the field E to be uniform between the plates at any instant and zero beyond the edge of the plates. Also assume, because of symmetry, the lined of the field to be circular on the plates. Edit View Insert Format Tools Table 12pt v Paragraph BIU
