Question:

Which of the following statements is incorrect regarding a transformer?

A Secondary current of a step-down transformer is less than its primary current.
explanation

A transformer is a static device so it has no mechanical losses. A transformer only transforms the voltage and the current and the frequency remains same during the transformation process. The power on primary side of an ideal transformer is equal to the power on the secondary side. The transformer is step-down then the voltage on secondary side must be less than the voltage on its primary side, which means that the current on secondary side must be higher than the current on its primary side.

The first time I took the Asvab I failed with a 29 without the use of this app and not studying. The second time I downloaded the app and used a book called Kaplan Plus 2020-2021, but less likely, the mayority of the time I used this app instead of the book and when I took the Asvab I scored a 50 + afqt, in need of a confirmation test too because I achieved a 20 points more than the last time. But I pass it thanks to this app. Most of the word Knowledge words that were in my asvab version were in the app ! and it’s important because the word Knowledge is the part that most helps you get a higher AFQT.

What else can i say other than this app is extremely good for free. Minimal adds and useful problems that even provide and explanation for the answer. I’d highly recommend this app.
