Three capacitors are connected to a battery as shown in the figurebelow. Their capacitances are C1 = 3C, C2 = C, and C3 = 5C.
(a) What is the equivalent capacitance of this set of capacitors(in terms of C)?
(b) State the ranking of the capacitors according to the chargethey store, from largest to smallest.
Q 2 > Q 3 > Q 4
(c) Rank the capacitors according to the potential differencesacross them, from largest to smallest.
5?V1 > ?V2 = ?V3
?V2 > ?V3 > ?V1
?V1 > ?V2 > ?V3
?V1 = ?V2 < ?V3
(d) Assume C3 is increased. Explain what happens to the chargestored by each capacitor.
6Q3 and Q1 increases; Q2 decreases.
Q3 and Q2 increases; Q1 decreases.
Q3, Q1, and Q2 increases.
All charges stay the same.
