Why transformer frequency is constant?

In transformer there is no rotating part.so frequency constant.


What happens when frequency is increased of transformer?

When the frequency of a transformer is increased, the core losses of the transformer increase due to increased eddy current losses and hysteresis losses. This results in a rise in temperature of the transformer. Additionally, higher frequency can affect the impedance of the transformer and alter the voltage regulation and efficiency.


Why frequency remains constant in transformer?

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....


What types of noise are frequency independent?

noise are assumed frequency independent......


The basic function of a transformer is to change?

The basic function of a transformer is to change voltage levels.


How input frequency to the transformer influences its physical dimension when using a step down transformer is used using as as a step-up transformer?

In general, the lower the frequency of operation, the more weight must be added to the core laminations to avoid magnetic field saturation. This increases the size and weight of the transformer as the frequency decreases.


Why is amplitude modulation susceptible to noise but not frequency modulation?

because noise usually changes the amplitude not frequency.


Does a transformer changes the frequency of incoming supply?

Yes the transformer effects the incoming frequency supply. This frequency is dependent on the core lamination of the transformer the weightier the core lamination the lesser will be the frequency we get and vice verse..


What is the function of intermediate frequency transformer?

intermediate frequency transformer (ift) acts as a band selective n/w. the ift which is 455 khz is then given to IF amplifiers which is then given to detector.


Can you use a transformer to convert modified sine wave to pure sine wave?

we cannot use transformer because transformer cannot change frequency . . .


What type of transformer is used to prevent electrical noise from passing from the primary winding to the secondary winding?

Shielded transformer


Which noise becomes a great importance at high frequency?
