A 2.50 x 10-6 F capacitor is charged to 754 V and a 6.80 x 10-6 F capacitor is charged to 563 Volt. These capacitors are then disconnected from their batteries. Next the positive plates are connected to each other and the negative plates are connected to each other. Find the potential difference across each and the charge on each?
A) Find the potential difference across the first capacitor.
B) Find the potential difference across the second capacitor.
C) Compute the charge across the first capacitor.
D) Compute the charge across the second capacitor.
