Two parallel plate capacitors X and Y have the same area of plates and same separation between them , X has air between the plates while Y contains a dielectric medium of epsi_(r) = 4. Calculate the potential difference between the plates of X and Y. |

Answer» Solution :LET potential difference between the PLATES be `V_X` and `V_Y` RESPECTIVELY , then `(V_(X))/(V_(Y)) = (C_(Y))/(C_(X)) = 4` and `V_(X) + V_(Y) = 15 V implies V_(X) = 12 V and V_(Y) = 3 V ` |
