A parallel plate capacitor is created when two large flat metal plates are separated by a distance d. The plates are connected to a battery. The face of each plate is A_1, as seen in Figure 1: A new capacitor is formed by attaching two uncharged metal plates, each with area A2 to the capacitor as shown in Figure 2: Consider the magnitude of the electric field between the plates. When the new plates are attached, what happens to the magnitude of the electric field? E stays the same E decreases E increases There is not enough information to tell

Solution

Here ,

as the capacitance C is given as

C = epsilon_0 * Area/seperation

as the Capacitance C is increased from A1 to A2.

hence , when new plates are attached.

the capacitance C will increase.
