QUESTIONS

Write the physical quantity having its unit coulomb/ volt. Is it a vector or a scalar quantity?

What meaning would you give to the capacitance of a single conductor?

What is the net charge on a charged capacitor?

Is there any conductor which can take unlimited charge?

Three capacitors each of capacitance C are connected in series. What will be the equivalent capacitance? If the capacitors be connected in parallel, then?

In a parallel-plate capacitor, the capacitance increases from $4\mathrm{\mu F}$ to $80\mathrm{\mu F}$ on introducing a dielectric medium between the plates. What is the dielectric constant (or relative permittivity) of the medium?

The capacitance of a charged conductor is C farad and its potential energy due to the charge is U. Write down the expression for the charge on the conductor.

A ‘thin’ metallic plate is placed between the parallel plates of a capacitor. What will be its effect on the capacitance? (by ‘thin’ is meant here that the plate is of negligible thickness).
