This can also be explained using only two formulae
C = AE(n - 1)/d
As we can see from the formula the increase in dielectric E results to increase in capacitance C
Also from
C = Q/V
An increase in the capacitance results in a decrease in the voltage or the electric field strength V while the charge increases meaning the capacitor stores a greater charge
It's A myschool
The dielectric reduces the electric field strength inside the capacitor, resulting in a smaller voltage between the plates for the same charge. The capacitor stores the same charge for a smaller voltage, implying that it has a larger capacitance because of the dielectric.
So the ans is A.
Myschool please correct the ans.
Dielectrics in capacitors serve three purposes: to keep the conducting plates from coming in contact, allowing for smaller plate separations and therefore higher capacitances; to increase the effective capacitance by reducing the electric field strength, which means you get the same charge at a lower voltage.
Answer is A
Actually guys, the purpose of dielectric material to capacitor does insulate and separate the plate from each other it's the EFFECT of dielectric material in capacitor that then increases the capacitance
C=E⁰A/d
C rep capacitance
E⁰ rep dielectric
A rep area of plates
d rep distance btw plates
SO MYSCHOOL'S CORRECT
