CapacitanceHard
Question
A parallel plate capacitor is charged and the charging battery is then disconnected. The plates of the capacitor are now moved, farther apart. The following things happen :
Options
A.The charge on the capacitor increases
B.The electrostatics energy stored in the capacitor increases
C.The voltage between the plates increases
D.The capacitance increases.
Solution
The charge on the capacitor remains constants
