EEE :: Electrostatics
- The electric field at a point situated at a distance d from straight charged conductor is
- capacitors are used for audio frequency and radio frequency coupling and tuning.
- at a point may be defined as equal to the lines of force passing normally through a unit cross section at that point.
- When a dielectric is placed in an electric field the field strength
- The force between two charges is 120 N. If the distance between the charges is doubled, the force will be
- Which of the following materials has the highest value of dielectric constant?
- at a point is equal to the negative potential gradient at that point.
- The sparking between two electrical contacts can be reduced by inserting a
- The units of volume charge density are
- What will happen to an insulating medium if voltage more than the breakdown voltage is applied on it ?
