What is an electric current that periodically changes direction?
There are two types of electric current, DC or direct current and AC or alternating current. The power delivery to homes in most places in the world is AC or alternating current. This is where the electrons are pushed one way then back the other way with usually 100 or 120 changes in direction per second. This produces 50 or 60 forward/back cycles every second called 50Hz or 60Hz.
The direction of a magnetic field produced by an electric current depends on the direction of the what?
Flow of the current.
What is the net movement of electric charges in a single direction?
An Electric Current :)
How does electric current travel?
the flow of electrons in a metal is called electric current . the conventional direction of electric current is shown from positive pole to negative pole
What is difference between current and electricfield?
the direction of current is the direction of electrons move. the dirction of electric field can be negative to positive
What is an alternating circuit?
an electric current that changes it direction or strength repeatedly
Electric current changes direction repeatedly is called?
AC current (alternating current) like in a wall outlet
Electric current in which electrons repeatedly change direction?
AC
What types of current changes direction repeatedly?
AC current (alternating current) like in a wall outlet
What type of electric current changes direction?
AC current (alternating current) like in a wall outlet
What is AC current?
An AC current (alternating current) is one that changes its direction continuously - typically at 50 or 60 Hertz (cycles per second).
What is the direction of flow of electric current in an electric current?
DC current
What are twokinds of electric current?
One distinction that is often made is between DC (direct current, flows in one direction) and AC (alternating current, changes direction many times per second).
Define alternating current definition?
The alternating current refers to the flow of the electric charge periodically and in the opposite direction. The polarity changes with the time..

What is ac and DC current?
AC stands for alternating current and means that the current changes directions, flipping repeatedly from positive to negative and back again.DC means direct current, the current only flows in one direction and does not change polarity.
What are the 4 effects of force?
there are not 4 but 3 effects of electric current - heating effect, magnetic effect and chemical effect of electric current
