The capacitor starts with a piece of dielectric material completely filling the space between the plates. Then, as the picture shows, we: 1. remove the dielectric, so the dielectric constant becomes 1. 2. disconnect the battery from the capacitor, by opening a switch. 3. bring the plates closer together. The steps are done in order, one after the other. The capacitor, with the dielectric between the plates, has a capacitance of 0.480 F. == Part (a) Homework Unanswered Due Feb 6th, 12:15 PM The battery has a voltage of 15.0 V and the dielectric constant of the dielectric material is k = 7.00. Determine the charge stored by the capacitor after step 1 has been completed. Note that we're looking for Q, where there is +Q of charge on one plate and -Q on the other.
