How is the construction of an ac ammeter different from an dc ammeter

Click For Summary
SUMMARY

The construction of an AC ammeter differs from that of a DC ammeter primarily in the measurement techniques employed. DC ammeters typically utilize shunt resistors and galvanometers, while AC ammeters often incorporate transformers or rectifiers to handle alternating current. To convert a DC ammeter into an AC ammeter, modifications such as adding a rectifier circuit are necessary to accommodate the changing polarity of AC signals. Understanding these differences is crucial for accurate current measurement in various electrical applications.

PREREQUISITES
  • Basic understanding of electrical circuits

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?
