It is a hammer because hammers are not examples of a simple machine
Try Socratic it helped me with this type of question
Might of had a different magnitude.
Sneaky question.
The secondary voltage will be zero.
Secondary voltage is the result of CHANGES in the primary voltage. That means the primary is energized with AC. The transformer in this question is energized with DC, which doesn't change. So there is no secondary voltage, this transformer doesn't work, and what you get out of it is: Smoke !
