Question:

Which value of current does the ammeter used in A.C. circuit measure?

Solution and Explanation

An ammeter in an AC circuit measures the **rms (root mean square)** value of the alternating current. The rms value gives an equivalent DC value that produces the same power dissipation as the AC.
