Question:
Which value of current does the ammeter used in A.C. circuit measure?
Which value of current does the ammeter used in A.C. circuit measure?
Show Hint
The rms value of an AC current or voltage is the value of a steady DC that would provide the same power in a resistive circuit.

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.
