The generators at the power station are built to deliver voltage/current
with alternating characteristics, and this is preserved all the way from the
generating station to your house. It's completely intentional, because AC
is much easier to handle, distribute, and make the conversions between
long-distance and short-distance transmission that need to happen along
the way.
One whose direction and voltage (hence current) alternate harmonically, the latter above and below 0V.
AC, Alternating Current.
AC, or alternating current.AC, or alternating current.AC, or alternating current.AC, or alternating current.
A current which changes its direction of flow again and again is known as alternating current.
It is called an alternating current
It alternates.
It's alternating current
Alternating Current
With alternating current the current flows alternately one way and then the other.
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.
