Il Two 10-cm-diameter electrodes 0.50 cm apart form a parallel- plate capacitor. The electrodes are attached by metal wires to the terminals of a 15 V battery. What are the charge on each electrode,
the electric field strength inside the capacitor, and the potential difference between the electrodes
a. While the capacitor is attached to the battery?
b. After insulating handles are used to pull the electrodes away
from each other until they are 1.0 cm apart? The electrodes
remain connected to the battery during this process.
c. After the original electrodes (not the modified electrodes of
part b) are expanded until they are 20 cm in diameter while
remaining connected to the battery?
