    Dielectric constant of the materials, k

    ohhhhhhhhhhhhhhhhhhhhhhhhhhhhhh, i got it now! so Q1 after = 72+32 = 104 uC and Q2 after = 120-32 = 88 uC 104/12*k = 88/20, then k=1.97? Thanks!

    Dielectric constant of the materials, k

    so Q1 becomes 72+32 and Q2 becomes 120-32? Then how do I find the new voltage?

    Hi LowlyPion, oops, my bad. The voltage is disconnected...

    Hi LowlyPion, The question didn't mention that but I think it's not disconnected. Thanks

    Dielectric constant of the materials, k

    Homework Statement C1 = 12uF, C2=20uF, and the capacitors are charged so that the voltage across each capacitor is 6V. When a dielectric material is inserted between the plates of C1, the charge on C2 changes by 32 uC. Calculate the dielectric constant of the material, k. (PS. C1 is parallel...
