What is an electric current that periodically changes direction?

∙ 14y ago
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 creates waves?
Oscillating charges. (Electric current that goes back and forth periodically.)
Energy carried by current?
For DC: power (in watts) = current (in ampere) x voltage (in volts). Energy = power x time, so energy = current x voltage x time (time in seconds). For AC, a power factor may have to be included (the cosine of the angular displacement between current and voltage). This is often near one, but it may be less.
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
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 current?
An AC current (alternating current) is one that changes its direction continuously - typically at 50 or 60 Hertz (cycles per second).
What is an alternating circuit?
an electric current that changes it direction or strength repeatedly
What type of electric current changes direction?
AC current (alternating current) like in a wall outlet
Electric current changes direction repeatedly is called?
AC current (alternating current) like in a wall outlet
What is the definition of commutator?
A commutator is an electrical switch that periodically reverses the current direction in an electric motor or electrical generator. A commutator is a common feature of direct current rotating machines.
What are the differences between AC power and DC power?
The description AC/DC refers to equipment designed to be operate on either alternating current (AC) or direct current (DC). In alternating current the movement of electric charge periodically reverses direction. In direct current , the flow of electric charge is only in one direction.
What is meant by alternative current?
Alternating current is more efficinent. It is wireless and more efficient than direct current. And it is safer. Plus Tesla is better than Edison
In which circuit does charge reverse direction many times per second?
In an alternating current (AC) circuit, the electric charge periodically reverses direction at a certain frequency. This is in contrast to a direct current (DC) circuit, in which charge flows in one direction only.
What is the direction of flow of electric current in an electric current?
DC current
What direction does wind always flow?
Direct Current, sometimes abbreviated DC. When the current periodically changes direction, that's Alternating Current (AC)
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).
