SUMMARY
The discussion centers on calculating the efficiency of a transformer given specific power and voltage parameters. The primary power is stated as 13W, with a primary voltage of 120V and a secondary voltage of 12V. The turns ratio is indicated with an unknown primary turns count (Np) and a known secondary turns count (90). The efficiency formula used is eff = Psec / Pri * 100, highlighting the need for clarity on the turns ratio to accurately compute transformer efficiency.
