Answer Posted / raina
400 hz is used in aircraft because this is the optimum
frequency. If frequency more than 400 hz used losses will
increase since most of losses increase with increase in
frequency and if lower frequency is used than size of the
component will increase.so 400 hz is the optimum frequncy
which provide the balance i.e. for the given size of
component or equipment losses is not that much high.
