What does the electric current have?
In metal conductors, electric current is the flow of electrons.
Name one metal that is purified on a large scale by electrolysis?
Aluminum is one metal that is purified on a large scale by electrolysis. It involves passing an electric current through a molten mixture of aluminum oxide and cryolite to extract pure aluminum metal.
What is an electric current through a metal?
It's flow of electrons under directing external electric field.
What is electrical energy converted into when electric current flows through the metal filament of a light bulb?
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
Why are metal bodes designed to store charge made from large hollow spheres?
Large hollow spheres are used for metal bodies designed to store charge because they have a uniform electric field inside and the charges remain on the outer surface. This design minimizes the potential for internal charges to interfere with the stored charge, and it also maximizes the amount of charge that can be stored due to the large surface area of the sphere.
What is a thin metal wire that is designed to melt when the electric current is to large?
A fuse.
What does the electric current have?
In metal conductors, electric current is the flow of electrons.
Electric current in a metal conductor is carried by?
Electric current in a metal conductor is carried by a wire. This wire has been specifically adapted to carry this current.
Why there is no current in a metal in the absence of electric field across it?
In the absence of an electric field, there are no external forces acting on the charges in the metal to generate a current. A current only flows in a metal when there is an electric field present to move the charges. Without an electric field, the charges in the metal remain stationary.
Name one metal that is purified on a large scale by electrolysis?
Aluminum is one metal that is purified on a large scale by electrolysis. It involves passing an electric current through a molten mixture of aluminum oxide and cryolite to extract pure aluminum metal.
What would you expect to conduct an electric current?
the metal
What does an electric current in a metal consists of to move?
An electric current in a metal consists of the movement of free electrons. These electrons are loosely bound to the metal atoms and can move freely throughout the material in response to an applied electric field.
How electric current flow in metal?
Electric current flows in metals due to the movement of free electrons. When a voltage is applied across a metal conductor, the electric field created causes the free electrons to move in the direction of the field, creating a flow of charge which we refer to as electric current.
How are electromagnets used in an electric bell?
In an electric bell, an electromagnet is used to create a magnetic field when an electric current flows through it. This magnetic field attracts a metal hammer, causing it to strike the bell and produce sound. The circuit is designed to intermittently break and connect the flow of current to create a ringing effect.
What electric current in a metal consist of moving?
Electric current in a metal consists of moving electrons, which are negatively charged particles that flow in response to an applied electric field. These electrons move through the metal's lattice structure, transferring energy and producing electrical conductivity.
Is the electric current in a metal conductor is carried by positive ions?
Yes
What element is a good conductors of thermal energy and electric current?
a metal
