1) If we charge a stacked capacitor like the one in the picture and then remove the leads (red and blue) what will be the voltage between bottom and top plate? Is it going to be 5 times (the number of stages) the original voltage or what? [PLAIN]http://img89.imageshack.us/img89/4742/capr.png [Broken] 2) If we take parallel plate capacitor and roll it up will the capacitance change? Surface area and distance between the electrodes will remain the same, but will the total area now increase (thus increasing the capacitance) because opposite electrodes will be close to each other (from the other side)? Or maybe electric field only exists between two plates? Thanks in advance.
