Electric current is defined as the rate of change of total charge flowing in a given time. It is measured in amperes (A), where 1 ampere is the flow of 1 coulomb of charge per second. Current (I) equals the total charge (q) divided by the time (t) taken, or can be expressed as the change in charge (dq) flowing across a cross-section over an infinitesimal time (dt). The standard unit of electric current according to the international system is the ampere.

1. 1. ELECTRIC CURRENT

2. Definition of Electric current?
The rate of change of total charge
flowing to time taken.

3. EC=Total charge flowing
Time taken
I= q/t
That is
If the flow of charges is not uniform then
current is given by
I=dq/dt
Where dq is the change that flows across
a cross-section in a time dt.

4. Unit of Electric current
The SI unit of electric current is ampere(A)
It is also known as practical unit of current and
denoted by the letter A.
The current through a conductor is said to be
one ampere.
