what is electric current
Answers
Answer:
1)Definition: Electric current is defined as the rate of flow of negative charges of the conductor. In other words, the continuous flow of electrons in an electric circuit is called an electric current. The conducting material consists a large number of free electrons which move from one atom to the other at random.
Explanation:
1)An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. In electric circuits this charge is often carried by electrons moving through a wire.
2)Physics Concept. Electric current is the rate of flow of charge. It is the quantity of charge that passes through a surface (for example the cross section of a wire) per unit time. In electric circuits we usually think of the amount of charge that passes through a point on a wire per unit time.
3)Electric Current Formula and Unit
If a charge Q flows through the cross-section of a conductor in time t, the current I then I=Q/t. The S.I unit of charge is coulomb and measurement of electric current happens in units of coulomb per second which is 'ampere'.
i hope it helpfull to you mate..
Electric Current : Electric Current is the directed flow of electric charges. The strength of the electric current is measured by the net charge flowing across a certain area per unit time
S.I unit of Current : S.I unit (International System of Unit) of Current is Ampere (A), named in the honor of French scientist Andre Marie Ampere (1775 - 1836)
