Assume a capacitor connected to a voltage source with a supply voltage of 15 v and a- 4 x 10-6 m2, d 3 x 10-3 m with the initial dielectric being free space. if we insert a dielectric with er 3, determine the magnitude of charge which will migrate onto or off of the plates of the capacitor. 9 x 10-13 c of charge leaving the plates 3,5 x 10-13 of charge leaving the plates 3.5 10-13 c of additional charge accumulating on the plates 9 x 10-13 c of additional charge accumulating on the plates
