then it changes only in proportion of frequency so increase
in corona loss by 25%

which %age of corona losses increses if frequency is increased to 25%...

Answer / neha

Corona loss is directly propotional to( f+25 ) where f is
the frequency. Suppose initially corona loss 100% , than
frequeny is 125%, after increases of 25% frequency corona
loss becomes 150%.

Increases in corona loss in % = [( 150 - 125 )/ 125 ]x 100

= 20%
