A laboratory technician connects the primary of an ideal transformer having Np=1000 turns to a 120V (rms) AC supply. When the secondary is connected to an ammeter and a 6Ω non-inductive resistor, the ammeter reads 8A (rms).
Based on these observations, answer the following:
a. (i) Calculate the rms secondary voltage.
b. (ii) Determine the number of turns in the secondary winding.
c. (iii) Find the rms current in the primary winding.
d. (iv) Classify the transformer as step-up or step-down and give a numerical justification.
