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.
an ac current (alternating current) changes direction
Alternating Current (AC). If it doesn't reverse direction it's Direct Current (DC).
alternating current
Alternating current, AC
Alternating current has this tendency.
Flow of the current.
Oscillating charges. (Electric current that goes back and forth periodically.)
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.
An Electric Current :)
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
The alternating current refers to the flow of the electric charge periodically and in the opposite direction. The polarity changes with the time..
An AC current (alternating current) is one that changes its direction continuously - typically at 50 or 60 Hertz (cycles per second).
an electric current that changes it direction or strength repeatedly
AC current (alternating current) like in a wall outlet
AC current (alternating current) like in a wall outlet
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.
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.
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 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.
DC current
Direct Current, sometimes abbreviated DC. When the current periodically changes direction, that's Alternating Current (AC)
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).
