In a simple capacitor that consists of two metal plates, the separating insulating material is called __________?

• Electrodes

• Electrolytes

• Bi-Electric

• Dielectric

True or false: The capacitance increases as the distance between the plates decreases.This action brings the plates closer together, creating a stronger electric field.
