AC voltage, like the voltage in your house, is typically referred to as 120vAC. This means the voltage swings 120V positive and 120V negative 60 times per second (60 Hz) 360 degrees total (sine wave). Current and voltage go hand-n-hand so the current alternates with the voltage. the RMS value is what we experience at the output (160vAC is actually sent to the circuits)
Transformer is based on the principal of mutual inductance.Induction is produced due to sinusoidal wave form thats why we use Alternating current inspite of Direct current.
Alternating current is a flow of electrical energy in which the direction of electron flow reverses periodically. The mains electricity in your house is likely Alternating Current. The other form is Direct Current, where the direction of electron flow is in one direction only. Such as the flow from the batteries in your flashlight.
Form factor of any periodic wave is [RMS CURRENT]/[AVERAGE CURRENT]. For sinusoidal wave RMS current=I/sqrt(2); AVERAGE current=2I/pi; Therefore, Form factor=[I/sqrt(2)]/[2I/pi] =pi/{2*sqrt(2)} =1.11
Yes, it is true that current supply from generating plants is an alternating current. There is no success found in bulk power generation of direct current ( D.C. ) in a power plant. But yes it is possible to transmit the power in the form of direct current ( High Voltage Direct Current Transmission-HVDC Transmission ) that possible after converting the generated alternating current into direct current with the help of high range converters.
The main advantage of using sinusoidal waveform is that any waveform can be represented using a sinusoidal wave (by applying Fourier series). Also, analysing a circuit (or any other system) becomes simpler and easier using sinusoidal signal as test signal.

All types of generators induce EMF in sinusoidal wave form. (A.C.) In a D.C. generator the function of a commutator is to convert A.C. EMF into D.C. The commutator rectifies the output that is the alternating current so as to produce unidirectional alternating current (pulsating DC). This reverses the negative polarity current to a positive one so as the output is a pulsating DC.

AC stands for "alternating current," which is a type of electrical current that periodically changes direction. It is not a wave but can be represented by a waveform, which shows how the voltage or current changes over time in a repetitive manner. So, AC is not a wave itself, but it produces a waveform when graphed.
alternating current electricity, or AC current, or AC.
sinusoidal Wave is the description of the shape that is seen on a oscilloscope display of, for example, true "House Current" The ramp wave form and step wave form are sharply different in shape and can cause problems with some electrical devices
A car only uses Direct Current. After it has been converted from Alternating Current generated by the alternator.
