First we know that transformer is a statical electrical device that transfer electrical energy from one circuit to another circuit with out change its frequency .....it may be voltage or current is change simultaneosuly or separately .... and point is why does not change the frequency in the transformer because the there is no moving part in transformer....As we know that frequency is depends upon the rotation....
because iron loss is depends on frequency and it is constant through out the operation ...irrespective from load
The basic function of a transformer is to change voltage levels.
The flux is set by the voltage applied to the transformer. In most applications, the voltage is constant, and therefore the flux is constant also.
No. A constant DC current of sufficient magnitude induces smoke in a transformer.
The DVDF (double voltage double frequency) test is an overvoltage withstand test. It is performed by applying a higher than nominal voltage (2 times) to the transformer for a relatively short period of time (usually 1 minute). Since a prolonged (significant) overvoltage will cause the transformer to overexcite, the volts per hertz are kept constant by applying a higher than nominal frequency (2 times in this case).
In transformer there is no rotating part.so frequency constant.
In a standard transformer, the ratio of input volts to output volts remains constant.
On AM broadcasts, the amplitude of the carrier wave remains constant. This means that the strength or power of the signal does not change, only the frequency of the signal is modulated to carry the audio information.
In simple harmonic motion, the frequency remains constant if friction is ignored.
In frequency modulation (FM) the amplitude does not remain constant. Instead, the amplitude varies according to the modulation index and the frequency of the modulating signal. This is in contrast to amplitude modulation (AM), where the amplitude of the carrier signal is modulated while the frequency remains constant.
If the speed of a wave remains the same while the wavelength stays constant, the frequency also remains unchanged. This is because the relationship between the speed, wavelength, and frequency of a wave is given by the equation speed = frequency x wavelength. So, if two of these values are constant, the third one will be constant as well.
a transformer or inductor or capacitor does not change frequency frequency is controlled at the generating station with the speed of the motor or turbine the number of phases will not make a difference an inductor or capacitor can shift phase up to 90 degrees you can make 3 phase power from single phase power with inductors capacitors and transformers

When sound enters another medium such as a wall, the frequency or pitch of the sound remains constant. The velocity or speed of sound may change depending on the properties of the medium, but the frequency remains the same.
As the frequency of a wave increases while the speed remains constant, the wavelength of the wave will decrease. This is because the speed of a wave is the product of its frequency and wavelength, according to the wave equation v = f * λ. So if the speed is constant and frequency increases, wavelength must decrease to maintain this relationship.
frequency modulation..
its frequency remains constant but velocity changes.
