Why is there no electric field in a conducting sphere?
Since field lines begin on positive charges and end on negative charges, every field line generated by the inner sphere must terminate on the inner surface of the outer sphere in order for there to be no electric field inside the conductor.
Why are there no charges inside a conductor?
The inside of the conductor does not contain any charge. If charges were present inside a conductor then such charges would produce an electric field and the electrons would move and cancel out the field neutralizing the charge.
What is the electric field inside a solid sphere?
Note: Since this is a solid sphere , it has charge inside it as well and that is why the electric field is non zero. In case of a hollow spherical shell, the electric field inside the shell is zero .
Can electric field inside a conductor be non zero?
Can the electric field inside a conductor be non zero? The answer is NO. Electric field inside a conductor is always zero. Reason: The electricity conducting free electrons are only present on the external surface of the conductor.
What is a negative charge called?
The atom that has lost an electron becomes a positively charged ion (called a cation), while the atom that picks up the extra electron becomes a negatively charged ion (called an anion).
What is the electric field inside a capacitor?
Electric field strength
In a simple parallel-plate capacitor, a voltage applied between two conductive plates creates a uniform electric field between those plates. The electric field strength in a capacitor is directly proportional to the voltage applied and inversely proportional to the distance between the plates.
What happens when an insulator is placed 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.
