A parallel-plate capacitor is charged through a 50 ? resistor by a 10 V battery. The plates are 10 cm×10 cm squares, 2 mm apart.
• It is known that during the capacitor's charge ?V_C (t)=?V_max ?(1-e?^(-t/?)); calculate ??V?_max to find the electric field between the plates as a function of time
• Use Maxwell-Ampère's equation to calculate the maximum strength of the B-field on the perimeter of the plates; when is the B-field maximum?
