If the charge on each plate has a magnitude of 5x10-6 C then the force exerted by one plate on the other has a magnitude of about:A. 0 B. 5N C. 9N D. 1 x104 NE. 9 x 105 NHITT2Each of the four capacitors shown is 500 μF. The voltmeter reads 1000V. The magnitude of the charge, in coulombs, on each capacitor plate is:A. 0.2 B. 0.5 C. 20 D. 50 E. none of theseCurrents and Resistance Current and current densityResistance and ResistivityThermal variationsOhm’s lawPower in Electrical CircuitsCurretns and Current DensityCurrent Current densityResistanceDrift velocityResistivityPower dtdqi Aij /IRV dnevj AlR /RVRiiVP /22materialsMetalsSemiconductorsInsulatorsSuperconductors (Florida connection)SuperconductorsJ.
