ELECTRIC CURRENT is defined as the amount of charges flowing through a conductor per unit time.SI unit of electric current is Amphere
ELECTRIC CURCUITis countinous and closed path of an electric current.
Answer:
An electric current is the rate of flow of electric charge past a point:2:622 or region.:614 An electric current is said to exist when there is a net flow of electric charge through a region.[3]:832 In electric circuits this charge is often carried by electrons moving through a wire. It can also be carried by ionsin an electrolyte, or by both ions and electrons such as in an ionized gas (plasma).
Electric current
A simple electric circuit, where current is represented by the letter i. The relationship between the voltage (V), resistance (R), and current (I) is V=IR; this is known as Ohm's law.

The SI unit of electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. The ampere (symbol: A) is an SI base unit:15 Electric current is measured using a device called an ammeter.
