Question
Please help.
If three unequal capacitors, initially uncharged, are connected in series across a battery, which of the following statements is true? The largest voltage appears across the capacitor with the smallest capacitance. The equivalent capacitance is greater than any of the individual capacitances. The capacitor with the largest capacitance has the greatest charge. The largest voltage appears across the capacitor with the largest capacitance. The capacitor with the smallest capacitance has the smallest charge. A parallel-plate capacitor is charged and then is disconnected from the battery. By what factor does the stored energy change when the plate separation is then doubled? It becomes four times larger. It becomes two times larger. It stays the same. It becomes one-half as large. It becomes one-fourth as large.Explanation / Answer
1)
The largest voltage appears across the capacitor with smallest capacitance
2) it becomes two times larger
