The frequency of any alternating current (ac) electrical supply always depends on the frequency at which the supply has been generated.
That is true no matter whether it was generated at a power station, for use in a home or factory, or in a dc-to-ac power inverter unit, for use in, say, a vehicle or boat.
Power stations in USA, Canada and other countries generate ac at 60 Hz.
Power stations in countries in Europe and other world areas generate ac at 50 Hz.
"Hz" is short for "hertz" which is the name used internationally for "one cycle per second".

Why a sine wave is a simple vertical line in a frequency domain?
A sine wave is a simple vertical line in the frequency domain because the horizontal axis of the frequency domain is frequency, and there is only one frequency, i.e. no harmonics, in a pure sine wave.
What is the diagram of ac current?
Sine wave
How do we measure AC sine wave using an oscilloscope?
To measure an AC sine wave using an oscilloscope, first connect the probe to the circuit where the AC signal is present. Set the oscilloscope to an appropriate voltage scale and time base for the expected frequency of the sine wave. Adjust the vertical and horizontal controls to clearly display the waveform on the screen. Once displayed, you can analyze the waveform by measuring parameters such as peak-to-peak voltage, frequency, and period directly from the oscilloscope's readout or by using the cursor function for more precise measurements.
What is the Symbol used for AC voltage?
a sine wave (~)
Which signal has a wider bandwidth a sine wave with a frequency of 100 hz or a sine wave with a frequency of 200 hz?
The signal that changes at a higher rate occupies greater bandwidth.
How is the speed of an AC motor that's being driven by a constantly changing sine wave voltage effected?
Assuming the sine wave's angular frequency is what's changing, the motor will speed up and slow down in proportion to that frequency.
What are the main differences between AC and DC currents?
An AC waveform is a sine wave and varies from positive to negative with a frequency of 60 Hertz (Cycles per Second). DC is a constant voltage and does not vary like the sine wave.
What is the relationship between the wavelength and frequency of a sine wave?
The wavelength and frequency of a sine wave are inversely related. This means that as the wavelength increases, the frequency decreases, and vice versa. The product of the wavelength and frequency of a sine wave is always equal to the speed of the wave.
What is the frequency of an AC sine wave that repeats itself 500 times in one fifth of a second?
2500 hz
Why a sine wave is a simple vertical line in a frequency domain?
A sine wave is a simple vertical line in the frequency domain because the horizontal axis of the frequency domain is frequency, and there is only one frequency, i.e. no harmonics, in a pure 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.
Why sine wave is unstable at low frequency?
The sine wave at low frequency is unstable because it can create strong currents that nobody can stop them from
How can you use sine wave in a sentence?
The sine wave, with its repeating pattern, can represent a single frequency with no harmonics.

What is the sine wave formula and how is it used to calculate the amplitude and frequency of a sine wave?
The sine wave formula is y A sin(Bx C), where A represents the amplitude, B represents the frequency, and C represents the phase shift. To calculate the amplitude, you can find the maximum value of the sine wave. To calculate the frequency, you can determine the number of cycles that occur in a given time period.
