A parallel-plate capacitor filled with air has plates of area 6.6×10?3m^2 and a separation of 0.39mm .
1.) Find the magnitude of the charge on each plate when the capacitor is connected to a 12-V battery
2.) Will your answer to part A increase, decrease, or stay the same if the separation between the plates is increased? Explain
3.) Calculate the magnitude of the charge on the plates if the separation is 0.81mm .
