4. Consider two situations Case Y: Two conducting parallel plates with area A and separated by a distance d form a capacitor, they are charged with a potential difference of and then disconnected from the battery. Case Z: The same conducting parallel plates in case Y with area A and separated by a distance d form a capacitor, they are charged with a potential difference of and then disconnected from the battery. After they are disconnected from the battery, a neoprene dielectric is inserted between the two plates. A = 9 x 10² m² d = 3 x 10² m = 9 V Fill in the following table with values for both Case Y and Case Z Capacitance Charge on Capacitor Potential Difference across Capacitor (Uniform) Electric Field magnitude in the middle of the capacitor Case Y Case Z
