The power factor of a sine wave is a measure of how effectively electrical power is being converted into useful work output, defined as the cosine of the phase angle (φ) between the voltage and current waveforms. It ranges from 0 to 1, where a power factor of 1 indicates that all the power is being effectively used (purely resistive load), while a lower power factor indicates the presence of reactive power, typical of inductive or capacitive loads. A power factor of 0 means that all the power is reactive and none is being converted to useful work.

What is the Integration of sine wave?
cos wave
Determine second third and 12TH harmonic of a sine wave?
A sine wave has no harmonics. It only has a fundamental, so the value of the 2nd, 3rd, and 12th harmonics of a sine wave is zero.
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).
Fourier series of sine wave?
The fourier series of a sine wave is 100% fundamental, 0% any harmonics.
Is a sine wave a symmetrical waveform?
Since a sine wave is described by the trigonometric sin(x) function, which is symmetrical, the sine wave is also symmetrical, unless there is a DC bias, in which case it is not. (It depends on your definition of symmetry)
What is the form factor of sine wave?
Form factor is (RMS value)/(average absolute value) For sine wave form factor = (1/sqrt(2))/(2/pi) = about 1.11
What form factor does Toshiba use?
form factor tell about the purity of sine wave
How do you calculate the form factor of a rectified sine wave?
i dont know,,,give me ans
What happen if you give square wave instead of sine wave to the transformer?
If a square wave is used instead of a sine wave in a transformer, the output power will operate at a different frequency. This will produces varying levels of voltage and amperage based on the wave.
How do you generate cos wave from sine wave?
By shifting the sine wave by 45 degrees.
What type of electrical waveform is produced by a Ferroresonant Power Supply?
Sine wave
Why voltage generation and distribution in multiples of 11?
due to the form factor .as the form factor of sine wave is 1.1 so, we use its multiples .
What is the Fourier transform of a sine wave?
The Fourier transform of a sine wave is a pair of delta functions located at the positive and negative frequencies of the sine wave.
What is a pure sine wave inverter?
The sine wave is a mathematical function that describes a smooth repetitive oscillation. An Inverter is an electronic device that converts power from one voltage to another.A pure sine wave inverter is a device that produces a smooth and consistent flow of electricity in the required voltage.The benefits of a pure sine wave inverter are that the device requiring the electricity from the inverter will not suffer from surges and lows in power output and as such the connected device will perform a lot better.
Definition of sine wave?
A sine wave is the graph of y = sin(x). It demonstrates to cyclic nature of the sine function.
How could you print out a sine wave of your voice on a laser printer?
The voice is not a sine wave.
Why you are considering sine wave as ac but not cosine wave?
Sine wave is considered as the AC signal because it starts at 0 amplitude and it captures the alternating nature of the signal. Cosine wave is just a phase shift of the sine wave and represents the same signal. So, either sine or cosine wave can be used to represent AC signals. However, sine wave is more conventionally used.
