Why is the electric field inside an insulator not zero?
This is attributed to the fact that the electrons are loosely bound to the nuclei and they are free to rearrange themselves until the net field becomes zero. But in an insulator the electrons are tightly bound to the nuclei. So they can resist movement even at more intense fields. So net field is not zero.
What are the properties of field line?
Properties of Electric Field Lines
- The field lines never intersect each other.
- The field lines are perpendicular to the surface of the charge.
- The magnitude of charge and the number of field lines, both are proportional to each other.
What happens if you place an insulator in an electric field?
When an insulator, also called the dielectric, is placed in an electric field, it gets polarised. The polarised dielectric reduces the effective electric field.
Can an electric field exist inside a conductor?
Properties of a Conductor in Electrostatic Equilibrium The electric field is zero inside a conductor. Just outside a conductor, the electric field lines are perpendicular to its surface, ending or beginning on charges on the surface. Any excess charge resides entirely on the surface or surfaces of a conductor.
At which region is the electric field at a maximum?
depletion region
Why is there no electric field at the center of a charged spherical conductor?
The direction of electric field is the same in the direction of electric force. Why is there no electric field at the center of a charged spherical conductor? At the center of a charged spherical conductor, mutual cancellation of forces occurs, resulting in zero net force at the center. So the electric field is zero.
Which of the following is a type capacitor?
Explanation: Ceramic capacitor, electrolyte capacitor and paper capacitor are fixed capacitors whereas tuning capacitors is a variable capacitor, hence it is the odd one out.
