A power tansmission line feeds input input power at 2200 V to a step down transformer with its primary windings having 3000 turns. Find the number of turns in secondary to get the power output at 220 V. |

Answer» Here, `E_(p) = 2200 V, n_(p) = 3000, n_(s) = ? E_(s) = 220 V` For a step down transformer, `(n_(s))/(n_(p)) = (E_(s))/(E_(p)) = (220)/(2200) = (1)/(10)` `n_(s) = (n_(p))/(10) = (3000)/(10) = 300` |
