why in transformers voltage given is in the multiple of 11
Answer Posted / k.prakashchandra
The answer given by me is wrong as 110V DC is equivalent to
110 Vrms AC.But form factor= rms value/absolute average
value and is = 1.11.If you take DC voltage is as average
value itself then Vrms=1.11 DC volts which is wrong as the
formula applies to only sinusoidal AC.Considering the line
voltage drop ,the voltage could have been increased to 110 V
from 100V in USA which was the first country to utilize
electricity.
