1. The problem statement, all variables and given/known data A 3500 pF air-gap capacitor is connected to a 32 V battery. If a piece of mica fills the space between the plates, how much charge will flow from the battery? 2. Relevant equations C= K*C_0 V= V_0/ K Q= C*V K of mica is 7 3. The attempt at a solution solved for the _0's and plugged into Q=CV i used (C/K) * (V*K) = (3500 *10^-12F)/7 * 32V*7 = 1.12*10^-7C its wrong but i dunno what else to do. help.
