Electrostatic P...

Assertion: If the distance between parallel plates of a capacitor is halved and dielectric constant is three times, then the capacitance becomes 6 times.
Reason : Capacity of the capacitor does not depend upon the nature of the material.

Which of the following is not a unit for electric potential?

A parallel plate air capacitor has a capacitance $$C$$.When it is half filled with a dielectric of dielectric constant $$5$$, the percentage increase in the capacitance will be :

A capacitor is charged by using a battery which is then disconnected. A dielectric slab is introduced between the plates which results in :

The difference in the effective capacity of two similar capacitors when joined in series and then in parallel is $$6\ \mu F$$. The capacity of each capacitor is :

An air filled parallel plate condenser has a capacity of $$2pF$$. The separation of the plates is doubled and the inter-space between the plates is filled with wax. If the capacity is increased to $$6$$pF, the dielectric constant of wax is.

Three capacitors of capacitances $$1 \mu F$$, $$2 \mu F$$ and $$4 \mu F$$ are connected first in a series combination, and then in a parallel combination. The ratio of their equivalent capacitances will be:

When a dielectric slab is introduced between the two plates of condenser then its capacity ___________.

A parallel plate condenser with oil (dielectric constant $$2$$) between the plates has capacitance $$C$$. If the oil is removed, the capacitance of capacitor becomes :

If dielectric is inserted in charged capacitor (battery removed ), then quantity that remains constant is.
