SUMMARY
The discussion focuses on calculating the peak current in the primary coil of a step-down transformer with a primary-to-secondary turn ratio of 4:1 and a secondary peak current of 12 A. Using the transformer equation, the relationship between primary and secondary currents is established as (4/1) = (Ip/12 A). The conclusion drawn is that the peak current in the primary coil is 48 A, based on the conservation of power principle, where P1 = P2 and P = IV.
