Two capacitors are connected in parallel. (a) Ifa third capacitor is now connected in parallel with the original two,does the equivalent capacitance increase, decrease, or remain thesame? (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 ofcharge 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, andhence stores less charge.
