Final answer:
It is false that more power can be drawn from a transformer in winter due to lower ambient temperatures, as power capacity is determined by electrical design and cooling methods, not seasonal variability.
Step-by-step explanation:
The assertion that more power can be drawn from a transformer during the winter because the ambient temperature is lower is false. While it is true that lower temperatures can improve the efficiency of a transformer by reducing thermal losses, the power capacity of a transformer is primarily determined by the electrical design, not the ambient temperature. Specifically, the capacity is related to the allowable temperature rise of the transformer's windings, which is a factor of both the electrical design and the cooling method used, but does not significantly change with seasonal temperature variations.
