Problem 67P
CE Predict/Explain Two capacitors are connected in parallel,
(a) If a third capacitor is now connected in parallel with the original two, does the equivalent capacitance increase, decrease, or remain the same?
(b) Choose the best explanation from among the following:
I. Adding a capacitor tends to increase the capacitance, but putting it in parallel tends to decrease the capacitance; therefore, the net result is no change.
II. Adding a capacitor in parallel will increase the total amount of charge stored, and hence increase the equivalent capacitance.
III. Adding a capacitor in parallel decreases the equivalent capacitance since each capacitor now has less voltage across it, and hence stores less charge.

ANSWER:
Step 1 of 3
(a)
Here we need to find whether the equivalent capacitance increases, decreases or remains same when a third capacitor is added to the two capacitors which are connected in parallel.
