What is the full form of AC in AC current?

we pronounce that this is AC current and this is AC voltage but what is the full form of AC?

Answer:
AC means ALTERNATING CURRENT

so called bcoz the magnitude of the current rises to a maximum in one direction,decreases to zero and then flows in the opposite direction to complete a cycle.Therefore,the direction of current in the circuit keeps on changing.
AC - Alternating Current

DC - Direct Current

In the case of AC, the direction of the voltage and current keeps alternating between positive and negative 50 times (60 times in US) a second.
AC is actually Alternating Current so its wrong to say AC Current and AC Voltage.

we must say Alternating Current and Alternating Voltage
AC stands for Alternating Current, because it alternates between positive and negative current 60 times a second (in North America, 50 in parts of Europe and many other places).
DC means Direct Current, as from a battery.
ALTERNATING CURRENT
AC simply stands for ALTERNATING CURRENT
alternate current (A.C)
current account
The full form of AC in AC current is
Alternating Current (or) ac cleared current
Sine wave
Alternating Current
ALTERNATING CURRENT
ac is alternating current quite simple.
Alternate Current
Alternating current.This current have no polarity.
Full form of A.C. is alternating current.
Alternate Current. Means at one moment of time it become to 1 while at another moment of time it becomes 0.
