A capacitor with circular parallel plates of radius 8.51 cm separated by a distance of 1.61 mm is briefly connected to 500-V battery just long enough so that one plate of the capacitor has a charge of 2.10 nC. The capacitor and battery are then disconnected from each other, and the capacitor plates are now connected instead (via ideal wires) to the two opposite ends of a resistor that has a square cross-section of 2.00 mm by 2.00 mm and a length of 6.63 cm. What current flows in the resistor immediately after this new connection has been made? The resistor is made of carbon, which has these properties: 3.50x 10-50m thermal conductivity 43.0 W/m/K specific-heat capacity 471 J/kg/K 3510 kg/m resistivity mass density melting point 3870 K
