Its actually a sine function graph. It illustrates the variation of voltage and current with time. Yeah voltage varies every second in your house, only reason you cant detect it is the high frequency( >60 hz) at which they are transmitted.

What is the RMS value of AC sinusoidal waveform?
General formula: square root of the square modulus averaged over a period:xRMS =1/T sqrt( integral (|x(t)|2dt) ) ,where x(t) is the signal and T is its period.If you solve it for sinusoidal waves, you get a 1/sqrt(2)~0.707 factor between peak amplitude and RMS value:xRMS ~ 0.707 XPK ~ 0.354 XPK-PK ~ ...
Why the waveform of no load current is not sinusoidal?
No load current is mostly inductive, hence the load current may not be a sine wave
What is firing angle in thyristors?
A sinusoidal AC waveform is divided up into 360 degrees, with the positive half and the negative half of the waveform combined into a kind of circle. The firing angle simply refers to the point on the waveform, as measured in degrees (thus 'angle') which the thyristor is triggered into conduction. Answer2: Firing angle is the phase angle of the voltage at which the scr turns on. There are two ways of turning an scr on..one is by applying a gate current or by applying a voltage across the scr until it becomes greater than the breakover voltage.... Answer3: Thyristor need gate current and voltage to make it conduct. The firing angle is the sinusoidal increasing voltage. As it rises a voltage is reached with enough power to fire to trigger the gate. That voltage is the angle considering that a sinusoidal is 360 degrees per cycle.
The rms value of sinusoidal 200v peak to peak wave is?
You can work this out yourself. For a sinusoidal waveform the rms value is 0.707 times the peak value. As you quote a peak-to-peak value, this must be halved, first. Incidentally, the symbol for volt is 'V', not 'v'.
What is a rectifier circuit?
The Rectifier is an electronic device, which converts an AC waveform(Usually a Bi-directional waveform with Zero Average value) to a Pulsating DC waveform (Uni-directional waveform with Nonzero Average value). As AC wave (Sinusoidal) has two half cycles, namely - Positive Half cycle & Negative Half cycle If a Rectifier does it's operation only in one half of the cycles, it is known as Half Wave Rectifier. Similarly, If a Rectifier does it's operation in both the half cycles, it is known as Full Wave Rectifier.
What is the waveform of AC through a straight wire?
Either sinusoidal, or can always be represented as a sum of sinusoids.
How the output characteristics of AC and DC generator vary from other?
AC generators have a varying waveform which is sinusoidal in nature, whereas a DC output is linear.
How the output characteristics of AC and DC generators vary from each other?
AC generators have a varying waveform which is sinusoidal in nature, whereas a DC output is linear.
What are the attributes of a sinusoidal waveform?
Amplitude, frequency/period and phase.
What is RMS value of an AC Sinusoidal Waveform and the power they carry?
Hi, RMS is voltage X .707 and the power is voltage X current. Hope that helps, Cubby
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).
What are the advantages of sinusoidal wave form?
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.
Can UPS Uninterruptible power supply be loaded with dynamic loads like motors and hydraulic pumps?
That depends on both the UPS and type of motor, so there is no simple answer.Many types of motor will not run correctly unless the AC power is true sinusoidal waveform, and many inexpensive UPS units do not provide a true sinusoidal waveform; so in this case it cannot be done.But in other cases it is possible.
What is the RMS value of AC sinusoidal waveform?

What is sinusoid?
What is a sinusoidal wave? This is a wave that appears to have curves. AC current/voltage. If you see a wave on a ossiloscope of what our AC (Alternating current) mains voltage that will be the answer to the question. DC (direct current) does not appear to have the same qualitys
What is the wave form of clipping circuit?
As a sinusoidal signal is clipped the waveform approaches a square wave.
Can transformer operate on triangular wave DC?
If its a triangular wave, its not DC, its AC, its just not sinusoidal. Can a transformer operate on triangular AC? Yes, but not as efficiently as on sinusoidal AC.
