The AC supply is sinusoidal by the electricity being produced in a rotating machine - the alternator - that spins coils of wired across a magnetic field. The voltage is proportional to the rate at which the coil is cutting across the field so maximum at the infinitesimally small point at which it is moving perpendicular to the field; minimum when moving for an equally tiny moment along the field lines. Since the coil is rotating, the voltage at any one point is therefore proportional to the instantaneous angle of the coil with the field. So we now have an angular relationship that is changing continuously through the full 360 º of each rotation, hence the voltage follows the sine of the angle, by basic trigonometry. Each complete turn (360º) therefore gives 1 complete cycle with the 0V crossings where the wire is effectively moving along the magnetic field lines for an extremely brief moment.

How does a ups recreate an ac sine wave?
By switching circuits or transistors that turn on and off the polarity. This usually results in a square wave output. Then capacitors charge and discharge to smooth out the square wave to resemble the AC sine wave. The better or more expensive the inverter, the closer to an actual sine wave it gets.
Is there a device that converts modified sine wave AC output from a generator to pure sine wave AC?
Well, a pure sine wave can only be produced as a pure sine wave. If it was modified to begin with, it would never be a pure sine wave. However, an actual generator should be supplying pure sine wave output, while something such as an inverter would be producing a modified sine wave.
What is the diagram of ac current?
Sine wave
What is the Symbol used for AC voltage?
a sine wave (~)
Why it is named sinusoidal wave or sine wave in ac?
It's called a sine wave because the waveform can be reproduced as a graph of the sine or cosine functions sin(x) or cos (x).
Is the output of half wave rectifier exactly a sinne wave explain?
If a sine wave is applied to a rectifier, and the sine wave is strictly AC (no DC offset), the output will be 1/2 the wave - it will be clipped near zero, as the diode prevents reverse voltages. So the output will NOT be a perfect sine wave.

a phase shifted sine wave of a different amplitude.

Is IC555 is an ac device or dc device?
it is DC powered, but can generate sawtooth or triangular wave AC if wired up properly. it cannot generate sine wave AC, although with an opamp wave shaping circuit the triangular AC waveform can be reshaped to a rough approximation of a sine wave.
What is distortion in analog electronics?
If you feed a sine wave through an amplifier that isn't exactly linear, the output will be distorted, not a pure sine wave. Distortion is the defect where the output from a device does not mirror the input.
Is sine wave analog wave?
A: ANALOGUE IT can be AC or DC it is up to the application involved An analog signal can be a sine wave, a square wave a sawtooth wave or any other varying waveform
Can a low pass filter be used as an integrator?
When a low pass filter is used with a sine wave input, the output is also a sine wave. The output will be reduced in amplitude and phase shifted when the frequency is high, but it is still a sine wave. This is not the case for square or triangular wave inputs. For non-sinusoidal inputs the circuit is called an integrator.
Does a rectifier convert an AC voltage into a DC voltage?
Yes, a rectifier can be used to convert AC into DC.Using a single rectifier, half of a sine wave voltage can be clipped off, which leaves the other half. The voltage not steady as only half of the sine wave appears at the output during one cycle. This is half-wave rectification. A more complicated rectifier arrangement can force both halves of the AC input to be delivered in the output. One half of the sine wave will be "flipped over" so the output voltage does not change polarity.In neither case will the output voltage be "steady" and further "smoothing" circuitry will be required to make the DC output. This is the function of filtering, and many DC supplies will incorporate this feature. Lastly, we also find that DC supplies often incorporate some kind of regulation, which makes the output voltages resistant to changes when the input voltage changes and/or the load on the supply changes.
