Question 463Electricity/Electronics - QMED70% to pass
When a transformer is used to step-down voltage, what statement is true?
AI Explanation
The correct answer is D) The low voltage winding is the secondary coil.
In a step-down transformer, the high voltage winding is the primary coil, and the low voltage winding is the secondary coil. This is because the transformer is used to reduce the voltage from the primary to the secondary side. The low voltage winding, being the secondary coil, receives the reduced voltage compared to the primary winding.
The other options are incorrect because: A) the low voltage winding is not part of the core, B) the primary coil is the high voltage winding, and C) the low voltage winding is properly insulated to handle the reduced voltage.
