Question

Choose true or false for each statement regarding a parallel plate capacitor.. The voltage of a disconnected charged capacitor remains the same when the plate area is decreased. The capacitance is inversely proportional to the plate separation d. The voltage of a connected charged capacitor decreases when the plate area is decreased. Submit Answer Tries o/2 Choose true or false for each statement regarding capacitors in a circuit. 12 If you connect two different capacitors in series in a circuit, then the charge on each of them is the same Three identical capacitors in series have one third the capacitance of each individual one. D lf you connect two different capacitors in parallel in a circuit, then the voltage across each of them is the same. Submit Answer Tries 0/2

Explanation / Answer

a) False . The capacitance is proportional to A/d the ratio of the plate area to the distance. When A is decreased, the capacitance falls and the voltage would increase.

b) True. The capacitance is proportional to A/d the ratio of the plate area to the distance

c) False.  When A is decreased, the capacitance falls and the voltage would increase.

d) False. If a capacitor is connected in series with a battery, then the potential difference between the plates is fixed and equal to the voltage of the battery. Therefore, if the capacitance changes, then the charge on the capacitor plates must change as well in order to keep the potential difference between the plates constant

e) True.

f) True. If the capacitance changes, then the charge on the capacitor plates must change as well in order to keep the potential difference between the plates constant
