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?
Given: The input voltage to the transformer is 2300V The number of turns in primary windings is 4000 turns The output voltage of the transformer is 230 V To find: The number of turns in the secondary coil. The number of turns in the secondary coil is given by: V2V1=n2n1 n1=4000; V2=230; V1=2300 n2=V1n1×V2⇒n2=2300400×230⇒400
