The primarycoil of a transformer has 1,711loops. The secondary coil has277,714 loops. The primary coil has a98 A current and 74 V.
a.) Is this a step-up or step-down transformer? How do youknow?Choose one of the following.Itis astep-up transformer because the secondary hasmoreloops than the primary. Itis a step-up transformerbecause the primarycurrent is greater than theprimaryvoltage. Itis astep-down transformer because alltransformers arestep-down transformers. Itis a step-downtransformer because the primarycurrent is greater than the primaryvoltage. Itis a step-down transformer because thesecondaryhas more loops than the primary. Itis astep-up transformer because all transformersarestep-up transformers.
b.) Determine the power of the primary coil.

d.) Calculate the voltage in the secondary coil.
V
e.) Calculate the current in the secondary coil.
