Question

42. Very large capacitors have been considered as a means for storing electrical energy. If we constructed a very large parallel plate capacitor of plate area 1.85 m2 using paper x-37) of thickness ї 5 m as a dielectric, how much electrical energy would it store at a plate voltage of 1 500 V? (eo8.85 x10-12 c^Nm^) a. 0.045 J b. 9.1 c. 910 J d. 1 800 e. 3 600 J
