How can I tell if the source is AC or DC

  1. Sep 4, 2008 #1
    A 24 V battery is connected to the primary input of a transformer having a turns ratio of 8. The voltage seen at the secondary output is:

    Now how can I tell if the source is AC or DC from this question????

    Re: transformer

    Good question. If the battery is made from electrochemical cells, it's DC. And I've never heard of an AC source referred to as a "battery". If they meant AC, it is a really weird way to word the question.

    It was a bit of a trick question from my teacher....luckily I got it right.......the answer is zero volts since a battery would be considered a DC source....therefore no output voltage
