Dielectrics

How is the capacitance of a parallel-plate capacitor affected by filling the space between the plates with an insulator ?

• C stable when the space between the plates is filled with an insulator, ε_r >1

• C reduces when the space between the plates is filled with an insulator, ε_r >1

• C increases when the space between the plates is filled with an insulator, ε_r >1

• C fluctuate when the space between the plates is filled with an insulator, ε_r >1
