A variable parallel plate capacitor and an electroscope are connected in parallel to a battery. The reading of the electroscope would be decreased by.

Two identical parallel plate capacitors are connected in parallel to a3 volt battery. The battery is disconnected and the two capacitors are joined in series, Fig. What is the potentail difference between A and B ?

In an electroscope the connecting rod and the leaves are all metals.

A parallel plate capacitor is charged and then disconnected from the battery. If the plates of the capacitor are moved farther apart

The plates of a parallel plate capacitor are connected to an ideal voltmeter. What will happen to the reading of the voltmeter if the plates of the capacitor are brought closer to each other in an insulating medium?

A parallel plate capacitor is charged by connecting is plates to the terminals of a battery. The battery remains connected to the condenser plates and a glass plate is interposed between the plates of the capacitor, then

Each plate of a parallel plate capacitor has a charge q on it. The capacitor is now connected to a battery. Now,

Each plate of a parallel plate capacitor has a charge q on it. The capacitor is now connected to a battery. Now,

Each plate of a parallel plate capacitor has a charge q on it. The capacitor is now connected to a battery. Now,

The separation between the plates of a parallel plate capacitor is made three times while it remains connected to a battery (A) the battery absorbs some energy (B) the electric field between plates remains same (c) the charge on the capacitor decrease by 66.7% (D) some work has to be done by an external agent on the plates
