A parallel-plate capacitor with area 0.280 m2 and plate separation of 4.80 mm is connected to a 4.00−V battery. (a) What is the capacitance? F (b) How much charge is stored on the plates? C (c) What is the electric field between the plates? N/C (d) Find the magnitude of the charge density on each plate. C/m2 (e) Without disconnecting the battery, the plates are moved farther apart: Qualitatively, what happens to each of the previous answers?
