What is current

Asked by Sharmahimanshi | 7th Dec, 2018, 08:52: AM

Expert Answer:

An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire.

It can also be carried by ions in an electrolyte.

The moving charged particles in an electric current are called charge carriers.
In metals, one or more electrons from each atom are loosely bound to the atom, and can move freely about within the metal.
These conduction electrons are the charge carriers in metal conductors.
 
The SI unit for measuring an electric current is the ampere,
which is the flow of electric charge across a surface at the rate of one coulomb per second.
