1. A Capacitor is discharging through a resistor. When the capacitor has lost a quarter of its charge, the voltage across the resistor is:
A) greater than the voltage across the capacitor.
B) equal to the voltage across the capacitor.
C) Zaro.
D) equal to the sum of the voltages across the battery and the capacitor.
E) less than the voltage across the capacitor, but greater than zero.
2. An air-FIlled parallel-plate capacitor is connected to a battery and allowed to charge up, and then disconnected from the battery. A slab of dielectric material is placed between the plates of the capacitor. After this is done, we find that:
A) the voltage across the capacitor has decreased.
B) the charge on the capacitor has decreased.
C) the charge on the capacitor has increased.
D) the voltage across the capacitor has increased.
E) the energy stored in the capacitor has increased.
I thought Second question answer was E.

Explain in detail, please!
