Solve the following problems given below:
Problem I: Calculate the equivalent capacitance of three capacitors C1 and C2 in parallel and C3 in series with the C1 and C2 combination. Let C1=8pF, C2=7pF, and C3=4pF.
Problem II: If a 12 volt battery is placed across the three capacitor circuit in the previous problem, find the net amount of energy stored in the circuit once the capacitors have charged.
Show all work, use additional paper if necessary. Thank you.
