What represents the power rating of the secondary winding of a transformer?

• A. VAprimary = Vprimary * Iprimary
• B. VAsecondary = Vsecondary * Isecondary
• C. Vsecondary + Isecondary
• D. VAsecondary = Psecondary / Pprimary

Answer: (B)

The power rating of the secondary winding of a transformer is represented by the product of the secondary voltage and the secondary current, which is captured in the formula VAsecondary = Vsecondary * Isecondary. This reflects the apparent power in volt-amperes (VA) that the secondary winding can deliver. In electrical terms, the power rating indicates how much power the transformer can handle without overheating or failing, making it essential for determining the transformer’s suitability for specific loads. By calculating the product of voltage and current in the secondary winding, one can assess the maximum output capability of the transformer under given conditions. This understanding is crucial for ensuring the transformer operates efficiently within its ratings and avoids potential damage from overload.
