I observed that most of the electrical equipment and generation in aircraft
takes place at a frequency of 400Hz. The reason i was told is that size
decreases as frequency increases, can any one please explain me what is the
formula on the basis of which this is happening and the theory behind it? many
have given me formula but please explain me the theory behind it.
