In group theory, an alternating group is a group of even permutations of a finite set.
An alternating function is a function in which the interchange of two independent variables changes the sign of the dependent variable.
When you plug something into the wall socket at home, (mains power) you are using alternating current, when you use something powered by a battery, you are using direct current.
Alternating adding and subtracting 100
Alternating current (AC) continually flows in one direction then it changes direction and flows the other way. This switching back and forth creates what is called a sinusoid or sine wave. Frequency is the rate of this back and forth switching in alternating current. Frequency is measured in Hertz (Hz) which is the number times a wave switches back and forth PER SECOND or better described as CYCLES PER SECOND.
Yes, Consider Un = (-1)^n*n = -1, 2, -3, 4, ...
some examples of symbols for permuation groups are: Sn Cn An These are the symmetric group, the cyclic group and the alternating group of order n. (Alternating group is order n!/2, n>2) One other is the Dihedral group Dn of order 2n.

Bridge rectifier
alternating quantity is a quantity that is alternating
AC, or alternating current.AC, or alternating current.AC, or alternating current.AC, or alternating current.
I find alternating between the breast stroke, the crawl and the back stroke works lots of different muscle groups, and as you are alternating between swims gives each muscle group a break/rest.
If the current is alternating, then it has the properties of a wave in the conductor, such as frequency, wavelength, amplitude, phase, group velocity etc.
"What is alternating current machine?"
Alternating current is normally produced by rotating the magnet in the coil of an induced alternating voltage. When connected to a circuit, an alternating current will flow.
Alternating Current is measured in Amperes.
The symbol for alternating current is: ~
If the current is alternating, the magnetic field will also be alternating.
