What are your thoughts? We can't just give you the answer -- you need to tell us what you know about the question. Like, how does a DC ammeter work? There are actually two common types of DC ammeters -- what are they and how do they work? What would you need to change in order to convert a DC ammeter into an AC ammeter?
