An electric current flows when electrons move through a conductor, such as a metal wire. Metals are good conductors of electricity. Electricity passes through metallic conductors as a flow of negatively charged electrons. The electrons are free to move from one atom to another.

What carries electric current in metals?
These conduction electrons can serve as charge carriers, carrying a current. Metals are particularly conductive because there are many of these free electrons, typically one per atom in the lattice.
How does conductor carry electric current?
Electrical conductors allow electric current to flow easily because of the make up of their atoms. In a conductor, the outer electrons of the atom are loosely bound and can freely move through the material when an electric charge is applied.
Which best carries electric current?
Metals like copper, silver and gold are very good conductors of electricity, that is, electrons may flow freely in those and most other metals because of how electrons are arranged around their nuclei. Other materials, like most plastics and ceramics, glass, rubber and teflon behave in the opposite way.
What is electric current answer?
An electric current is a flow of particles (electrons) flowing through wires and components. It is the rate of flow of charge. If the electric charge flows through a conductor, we say that there is an electric current in the conductor. In the circuits using metallic wires, electrons constitute a flow of charges.
What particles carry electric current through solution?
Salt molecules are made of charged sodium ions and chlorine ions. When you put salt in water, the salt dissolved into solution. Water molecules pull the sodium and chlorine ions apart so they are floating freely. These ions are what carry electricity through water, as these charged particles can freely move.
What causes current?
Currents are cohesive streams of seawater that circulate through the ocean. ... Currents may also be caused by density differences in water masses due to temperature (thermo) and salinity (haline) variations via a process known as thermohaline circulation.
What are the charged particles that carry an electric current through a circuit?
The particles that carry charge through wires in a circuit are mobile electrons. The electric field direction within a circuit is by definition the direction that positive test charges are pushed. Thus, these negatively charged electrons move in the direction opposite the electric field.
What is meant by an electrical conductor?
Some materials let electricity pass through them easily. These materials are known as electrical conductors. Many metals, such as copper, iron and steel, are good electrical conductors.
What is electric current class 12th?
Hint: Electric current is defined as the rate of flow of charge per unit time through a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. ... Ampere is defined as one coulomb of charge moving past a point in one second.
What is electric current for class 10th?
Electric Current: The amount of flow charge through any cross-sectional area of a conductor in unity time is called Electric Current. Unit of Electric Current: It is CS-1 (coulomb per second) or Ampere (A). Electric Current is a scalar quantity. It is measured by an ammeter.
What metal is used as a conductor?
Copper. One of the most commonly used metals to conduct electricity is copper. As a material, copper is pliable, easy to wrap or solder, which makes it the best choice when large amounts of wiring are needed. Copper's core electrical function is related to the transmission of electricity and power generation.
What produces electric current?
To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. The pathway to carry the charges is usually a copper wire.
How do you find the current in a conductor?
The current is the ratio of the potential difference and the resistance. It is represented as (I). The current formula is given as I = V/R. The SI unit of current is Ampere (Amp).
How does electric current flow in a circuit?
In a closed loop or closed circuit the electrons flow through the connecting wires and parts such as lamps from the negative terminal or connection to the power source and back to the positive terminal. ... Electrons flow from the negative to the positive when a wire is attached to the terminal of the battery.
