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.

What happens to the frequency of a wave when the energy is increased?
When the energy of a wave is increased, the frequency remains the same. Frequency is determined by the source of the wave and does not change with energy.
What happens to frequency if time period is increased?
If the time period is increased, the frequency decreases inversely proportionally. This is because frequency is the reciprocal of the time period. So, as the time period increases, the frequency decreases.
What happens to a sound if the frequency is increased?
If the frequency of a sound wave is increased, the pitch of the sound also increases, making it sound higher. This means that the number of complete cycles of the wave occurring in a second is increased.
Why the transformer size decreases when frequency increased?
When frequency is increased in a transformer, the core material has less time to magnetize and demagnetize, reducing the core losses. This allows for a smaller core size to achieve the required magnetic coupling. Additionally, higher frequency transformers can use smaller windings due to skin effect, where current tends to flow on the surface of the conductor at higher frequencies, reducing copper losses and allowing for smaller conductors.
What happens to a wavelength when the amplitude and frequency are both increased?
When the amplitude and frequency of a wave are both increased, the wavelength remains constant. Amplitude affects the intensity or loudness of the wave, while frequency determines the pitch. Therefore, changing the amplitude and frequency does not alter the wavelength of the wave.
What happens to the pitch of a note when the frequency is increased?
If the frequency of a sound is increased, the pitch goes higher.
If the frequency is drop What will happens a step up transformer?
If the frequency drops, then overall impedence reduces and hence the current tend to increase, leading to over heating and ultimately may damage the transformer
Why transformer frequency is constant?
In transformer there is no rotating part.so frequency constant.
What happens to the frequency of a wave when the energy is increased?
When the energy of a wave is increased, the frequency remains the same. Frequency is determined by the source of the wave and does not change with energy.
What happens to frequency if time period is increased?
If the time period is increased, the frequency decreases inversely proportionally. This is because frequency is the reciprocal of the time period. So, as the time period increases, the frequency decreases.
What happens to the frequency of the wave as the tension on the wire is increased?
Don't cheat on your homework...
What happens to the total impedance of a series RC ciRCuit as the frequency is increased?
when the frequency is increased the total impedance of a series RC circuit is decrease.
What happens to a sound if the frequency is increased?
If the frequency of a sound wave is increased, the pitch of the sound also increases, making it sound higher. This means that the number of complete cycles of the wave occurring in a second is increased.
What happens to the frequency of the waves on a wire as the tension on the wire is increased?
they become smaller and faster
Why the transformer size decreases when frequency increased?

What happens to the wavelength of a wave when the energy is increased?
If you are talking about an electromagnetic wave; energy is proportional to frequency (E=hf), and frequency is inversely proportional to wavelength (wavelength equals velocity divided by frequency). So when the wavelength is increased, the energy is decreased.
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....
