transformer is a static machine that can change the voltage from one level to another level without any change in power and frequency
ie when vtg reduces in secondary the current increases so as to keep the power in same value
V1I1 =V2I2
IN CASE OF POWER TRANSFORMERS THE SECONDARY CURRENT CAN BE EASILY FOUND OUT BY JUST DIVIDING THE kVA RATING BY .75
