220V/50HZ - less frequency of sine wave propogation has
large distacve between alternation of current between Phase
& Neutral and gives 220V at Phase to Neutral on 50Hz
Frequency. simply lenthy propogation with higher voltage.
(Depends upon the LT Power transformer output)
120v/60HZ - High frequency of sine wave propogation has
less distacve between alternation of current between Phase
& Neutral and gives 120V at Phase to Neutral on 60Hz
Frequency.simply fast propogation with lower voltage.
(Depends upon the LT Power transformer output)
