consider two parallel rectangular conducting plates each of area A = 1.5 m separated by a distance d = 0.25 mm forming a parallel-plate capacitor. The region between the plates contains vacuum and the electric field strength in the region between the plates is 0.27 N/C. A battery provides a potential difference between the plates. 6. What is the voltage rating of the battery? 7. Compute the capacitance of the capacitor? 48. What is the charge of the capacitor?
