The ratio of the secodnary to the primary turns in a transformer is 3:2 and the output power is P. neglecting all power losses, the input power must be

The turns ratio of an ideal transformer is 1:n. the input to output power transfer ratio is

Transformer is a device used to increase or decrease the voltage in the transmission line according to requirement, Generally the input line voltage is fed in a primary coil and the output line voltage is obtained from the terminals of another coil In an ideal transformer, the primary and secondary coils are linked is such a way that there is no loss of magnetic flux and electrical energy. In an ideal transformer, if the number of turns and input voltage across the terminals of the primary coils be N_1 and V_1 , then the output voltage at the two terminals of the secondary coil V_2=V_1.N_2/N_1 , where N_2 is the number of turns in the secondary coil . The ratio of number of turns of the primary and secondary coils of an ideal transformer is 2:1 IF the input voltage is 440 V, then output voltage is if the input power of the transformer be 44 W, then output power is In the above mentioned transformer the input and output currents are respectively.
