Solve the following capacitance problems and show your solution:

2. A parallel plate capacitor has square plates of side 5 cm and separated by a distance of 1 mm. (a) Calculate the capacitance of this capacitor. (b) If a 10 V battery is connected to the capacitor, what is the charge stored in any one of the plates? (The value of ɛo = 8.85 x 10-12 Nm² C-²) Solution (a) The capacitance of the capacitor is E,A_ 8.85x1012 x25×10 C= = d 1x10 = 221.2 x10-13 F C = 22. 12 x10-12 F = 22 .12 pF (b) The charge stored in any one of the plates is Q = CV, Then = 22.12 x10-12 x10 = 221.2 x10-12 C = 221.2 pC
