Problem: Three capacitors, C1 = 4.00 µF, C2 = 2.00 µF, and C3 = 7.00 µF, are connected together. Find the effective capacitance of the group for the following situations.
Situation I: if they are all in parallel
µF
Situation II: if they are all in series
µF
If possible just a brief explanation how you got the answer?
