SUMMARY
The discussion centers on calculating the number of turns on the secondary coil of a transformer used in a battery charger, which converts 240V to 15V. Using the transformer turns ratio formula, V1/V2 = n1/n2, where V1 is the primary voltage (240V), V2 is the secondary voltage (15V), n1 is the number of primary turns (6400), and n2 is the number of secondary turns, the calculation yields n2 = (15 * 6400) / 240, resulting in 400 turns on the secondary coil. This method is essential for understanding transformer design and operation.
