When an electric field is applied to a conductor does the electric field develops within the conductor or around the conductor?
SidharthD
The electric field will develop inside the conductor, depending on the characteristics of the electric field -- in a steady state (DC) or in an alternating mode (AC). The higher the frequency of oscillation, the shallower the field will reside in the conductor -- skin depth (check the related link). Hence, when the frequency is high, only the few mm's of the outer skin participates in the action (AC electrical conduction.) In steady state (DC), the frequency is zero, the electric field is distributed inside the whole conductor.

Is plastic wrapped around the electric wires is a good conductor?
Plastic wrapped around the wire is insulator. Not a conductor. That is why it is wrapped around the conductor wire.
Created around a conductor when electrons flow through that conductor?
Then an 'electrical current' is said to be present in the conductor.
How electric current causes magnetic field around conductor?
Electric current causes magnetic field around conductor by producing a moving electric charges and the intrinsic magnetic moments of an elementary particles that is associated with a fundamental quantum property.
What does a Clamp-on ammeter do?
It is an electrical device with two jaws that open to allow clamping around an electric conductor. This allows the current in the conductor to be measured.
What is magnetic effect of electric current?
A magnetic field is induced around any conductor carrying an electric current.As explained in the Oersted Theory.
What is the relationship between electricity and magnetism with an electromagnet?
Oesterd discovered that when an electric current flows through a conductor a magnetic field develops around the conductor. So when you switch on the electromagnet a current passes through a solenoid generating a magnetic field which can be controlled by either forming more or less loops or increasing/decreasing the amount of current passing through the solenoid.
What electric charge crates a magnetic field?
Moving charges produce magnetic fields.Answer 2In other words, when the charge moves along a conductor it creates an electric current. The current induces a magnetic field around the conductor.
How do tongtester is working?
Tong tester is an electrical device having two jaws that allow clamping around an electrical conductor. It helps to measure the electric current in the conductor.
What form around a wire carrying an electric current?
Electromagnetic fields form around any current carrying conductor.
When is a conductor said to be in ''electrostatic equilibrium''?
That means that no electric forces act on charges, and therefore, charges won't move around.
Explain free electron concept and electric current?
the flow of electrons in semi conductor is called electric current. the electrons revolved around the nucleas is called free electrons
Why is electric potential inside a ring conductor on a conducting paper that has elctric field zero?
As long as there is any electric potential, charges continue moving around, until everything is balanced.
