Electrostatic P...

Eight identical spherical mercury drops charged to a potential of 20 v each are coalesced into a single spherical drop:

To obtain $$3 \mu F$$ capacity from three capacitors of $$2 \mu F$$ each, they will be arranged as follows:

When a thin mica sheet is placed between the plates of a condenser then the amount of charge, so compared to its previous value, on its plates will become:

Name the unit of electrical potential :

Electric potential is :

Let S be the set of all points in a plane. Let R be a relation on S such that for any two points a and b, aRb iff b is within 1 cm from a. Then R is

1 volt = ?

When a dielectric is introduced between the plates of a condenser, the capacity of condenser :

The equivalent capacitance in the given circuit is

what is the potential difference between two points, if 2J of work must be done to move a 4 mC charge from one point to another is:
