In a capacitor, the amount of dielectric stress is proportional to the

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.
