Why are higher frequencies better?

The main advantage of higher frequencies is that they require shorter antennas for decent reception quality, and that’s important for mobile devices. They also allow a wider band for modulating signals, so you can obtain higher frequency transmission.

Why transformer is a constant frequency?

It is clear that the frequency of output/induced voltage Vin is ω which is same as that of the input current. Hence, in a transformer, the frequency remains unchanged (constant) as flux changes.

What happens when frequency is increased?

The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

Are higher frequencies more powerful?

The faster you create the waves also increases the energy. In energy terms amplitude is roughly linear with energy. The frequency is squared in terms of energy. So yes, higher frequencies are relatively much more powerful than lower frequencies.

Why is lower frequency better?

One advantage of lower frequencies is that the signals have better penetration, meaning they pass through objects such as walls with less attenuation. The primary advantage of lower frequencies, however, is that lower-frequency radio signals propagate farther in the environment.

Why the transformer volume reduces with higher frequency?

The higher your flux is the more steel you need in your transformer in order to keep the flux density at a reasonable level, so that means higher frequency transformers can be smaller. The length of time between cycles where the transformer is charging the iron core decreases with the increased frequency.

Do transformers care about frequency?

It just means that the transformer is being used at other than the design optimum. The bottom line is that for continuous operation, the rated voltage for a power transformer should be respected for frequencies at or above the design frequency.
