Master h points SerCP9 16 P 031 arallel-plate capacitor with area 0.800 m2 and plate separation of 4 area 0.800 m2 and plate separation of 4.00 mm is connected to a 15.00-V battery. (a) What is the capacitance? b) How much charge is stored on the plates? (c) What is the electric field between the plates? N/C (d) Find the magnitude of the charge density on each plate (e) without disconnecting the battery, the plates are moved farther apart Qualitatively, what happens to each of the prevlous answers Tu This answer has not been graded yet Need Help?

Explanation / Answer

(a) Capacitance, C =  k.0.A/d
= 1.00 * (8.85 * 10^-12) * (0.80) / (4.00 * 10^-3)
= 1.77 * 10^-9 F

(b) Q = VC = 15.0* 1.77 * 10^-9 = 2.65x10^-8 C

(c) E = V/d = 15/4.00 * 10^-3 = 3750 V/m or 3750 N/C

(d) The surface-charge density on each plate=q/A = 2.65x10^-8/0.80 = 3.31x10^-8 C/m^2
