I I am asked question please give right answers..
you have no answer don't type
so my first question is
what is electric current??
so my second question is
what is an electric circuit??
so my third question is
give the SI unit of electric current??
so my 4th question is
define one ampere??
my 5th question is
explain the following open circuit??
so my 6th question is
explain the following closed circuit??
so my 7 question is
name the two types of current named in an electric circuit??
so my 8 question last question is
which of these given the directions of current in the electric circuit??
please right answer

Answer:
1) An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume.
2)An electrical network is an interconnection of electrical components or a model of such an interconnection, consisting of electrical elements. An electrical circuit is a network consisting of a closed loop, giving a return path for the current.
3) The ampere, symbol A, is the SI unit of electric current
4)Named for 19th-century French physicist André-Marie Ampère, it represents a flow of one coulomb of electricity per second. A flow of one ampere is produced in a resistance of one ohm by a potential difference of one volt.
5)An open circuit implies that the two terminals are points are externally disconnected, which is equivalent to a resistance R=∞ . This means that zero current can flow between the two terminals, regardless of any voltage difference.
6)Closed circuit means a complete electrical connection around which current flows or circulates. When you have a series of electrical wires connecting to each other and completing a circuit so that current travels from one end of the circle to the other, this is an example of a closed circuit.
7)There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction
8)The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery.
hope it help
Answer:
ANSWER =1
an electric current is an steam of charged particles such as electrons or iron.
ANSWER=2
an electrical network is an interconnection of electrical component or a model such an interconnection consisting of electric element
ANSWER=3
the SI unit of electric current is ampere
ANSWER=4
an ampere is an unit of measure of the rate of electron flow or current in an electric conductor . one coulomb of electric charge (6.24×10 ) charge carries
ANSWER=5
an open circuit is an circuit where the path has been interrupted or opened at some point so that current will not flow.
ANSWER=6
a complete electric connection around which current flows or circulate
ANSWER=7
serious circuit or parallel circuit
ANSWER=8
the positive terminal to the negative terminal of battery.
