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....

Why are iron losses constant at all loads in a transformer?
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?
The basic function of a transformer is to change voltage levels.
Is mutual flux in transformer constant for all loads?
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.
Can a constant dc current induce a steady state voltage in a transformer?
No. A constant DC current of sufficient magnitude induces smoke in a transformer.
Why dvdf test is required in 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).
Why transformer frequency is constant?
In transformer there is no rotating part.so frequency constant.
On AM broadcasts what remains constant?
the frequency!:-)
What remains unchanged in transformer action?
In a standard transformer, the ratio of input volts to output volts remains constant.
Why frequency is constant in a single phase transformer?
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 what remains constant?
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.
Why are iron losses constant at all loads in a transformer?
because iron loss is depends on frequency and it is constant through out the operation ...irrespective from load
When modulation frequency is double the modulation index is halF and the modulating voltage remains constant the modulation system is?
frequency modulation..
What happens to light when it travels from air into denser?
its frequency remains constant but velocity changes.
What frequency of waves increases wavelength .?
When the frequency DECREASES, the wavelength INCREASES, and vice versa.This assumes the speed of the wave remains constant.
What happens when you increase the speed of a wave what happens to the wavelength?
If the frequency remains constant, then the wavelength increases.
What happens to the wavelength the if we increase the frequency of vibration?
Provided the speed of the wave remains constant, as we increase the frequency of wave then wavelength decreases. Because frequency and wavelength are inversely related.
If the speed of a wave doubles while the frequency remains the same what happens to the wavelength?
The wavelength stays constant.
