Answer :
Final answer:
Buck boost transformers connected to buck have subtractive input, primary and secondary voltages. The output voltage of a transformer can vary based on the number of loops in the coils, with a step-down transformer decreasing voltage. Therefore correct option 1) True
Explanation:
When buck boost transformers are connected to buck, the input voltage, primary, and secondary voltages are subtractive. For a step-down transformer, the primary voltage is higher than the secondary voltage, indicating a reduction in voltage level.
The output voltage of a transformer can vary depending on the ratio of the number of loops in the coils. A step-down transformer decreases voltage, making the primary higher than the secondary voltage.
