The empty space between the plates of a capacitor is filled by a liquid of dielectric constant K, the capacitance of capacitor

The empty space between the plates of a capacitor is filled by a liquid of dielectric constant K, the capacitance of capacitor Correct Answer increases by a factor K

Concept:

  • The capacitance of a capacitor (C): The capacity of a capacitor to store the electric charge is called capacitance.
    • The capacitance of a conductor is the ratio of charge (Q) given to the conduction to the rise in its potential (V).

​C = Q/V

  • The unit of capacitance is the farad, (symbol F ).
  • If a dielectric medium is filled in a capacitor then the capacitance of the capacitor changes.
  • The capacitance, C = K C0 where C0 is the capacitance without the dielectric.

So Dielectric constant (k) = C/C0

  • The dielectric constant of a medium is the ratio of the electrostatic force of interaction between two given point charges held certain distance apart in vacuum/air to the force of interaction between the same two charges held the same distance apart in the material medium.

Explanation:

When the empty space between the plates of a capacitor is filled by a liquid of dielectric constant K, the capacitance of the capacitor increased by the factor of K.

The capacitance, C = K C0 where C0 is the capacitance without the dielectric.

A tank has an optional adjustable outlet pipe that can be attached to the tank at any height we want. This outlet pipe drains water from the tank at a constant rate, while the tank is being filled using another inlet pipe at a constant rate. If the outlet, pipe is attached at half the height of the tank, the tank, which is initially empty gets filled in 18 hours. If the outlet pipe is attached at height equal to two third height of the tank, the tank, which is initially empty, is filled in 16 hours. In how many hours will the tank, which is initially empty, be completely filled if the outlet pipe is not attached to the tank?
