A power transmission line feeds input power at 2300 V to a step- down transformer with its primary windings having 4000 turns. What should be the number of turns in the secondary in order to get output power at 230 V?

Text Solution

Verified by Experts

`E_(p) = 2300 V,N_(p)= 4000, E_(S) = 230 V`
`(E)_(s)/(E_(P)=(N)__(S)/( N_(P)`,thherefore`N_(s) = N_(p)xx(E_(s))/(E_(P)) = 4000xx (2300)/(2300) = 400`
