Answer
capacitance of capacitor.
Explanation
Dielectrics are non-conducting materials or insulators or bad conducting materials.Examples for dielectrics are glass, mica,Plastics etc.Dielectrics are placed inside two parallel plate capacitors. If larger the value of dielectric constant more charge can be stored.The electric field between two parallel plate capacitor is proportional to the capacitance of the capacitor.By the presence of dielectric the electric field strength reduced, so more charge can be stored.
