Electrical potential at the centre of a charged conductor is:

In a cathode ray oscillograph, the focussing of beam on the screen is achieved by

When two capacitors of capacities $$3\mu F$$ and $$6\mu F$$ are connected in series and connected to $$120 V,$$ the potential difference across $$3\mu F$$ is:

If $$C_1=3pF$$ and $$C_2=2pF$$, calculate the equivalent capacitance of the network shown in the figure between points A and B?

Find the charge appearing on capacitor of capacitance $$4\;\mu F$$ :

Condensers of capacities $$2\mu F$$ and $$3\mu F$$ are connected in series and a condenser of capacity $$1\mu F$$ is connected in parallel with them. The resultant capacity is:

What is the equivalent capacitance of the system of capacitors between $$A \mbox{ & } B$$?

If $$4\times 10^{20}eV$$ of energy is required to move a charge of 0.25 coulomb between two points, the p.d between them is:

A capacitor stores $$60\space\mu C$$ charge when connected across a battery. When the gap between the plates is filled with a dielectric, a charge of $$120\space\mu C$$ flows through the battery. The dielectric constant of the material inserted is :
