The Total solution for NCERT class 6-12
A power transmission line feedsinput power at 2300 V to a stepdown transformer with its primary windingshaving 4000 turns. What should be the number of turns in the secondary in orderto get output power at 230 V?
Input voltage, V1 =2300
Number of turns in primarycoil, n1 = 4000
Output voltage, V2 =230 V
Number of turns in secondary coil= n2
Voltage is related to the numberof turns as:
Hence, there are 400 turns in thesecond winding.
