A parallel plate capacitor has plates of an area of area.0066 m squared and a separation of.45 mm. (a)Find the magnitude of the charge on each plate when the capacitor is connected to a 12-V battery. (b) will your answer to part (a) increase ,decrease,or stay the same if the separation between the plates is increased. explain.(c) calculate the magnitude of the charge on the plates if the separation is .90 mm.
