What is the ratio of the number of turns in the primary

Reference no: EM13646952

A transformer is used to operate a model train. The transformer,which is plugged into a standard electrical outlet, produces anoutput voltage of 13.3 V (rms), applied tothe train's tracks. (The voltage supplied to transformer from outlet is 120 V.)

a) What is the ratio of the number of turns in the primary to the number of turns in the secondary?
b) If the train uses an average power of 13.7 W, what are the rms currents in the secondary and in the primary? Assume an ideal transformer, with no energy loss.
