Most of AC meters are calibrated to read
Correct answer: C. rms value
- A. average value
- B. peak value
- C. rms value
- D. mean square value
Explanation
Most AC meters, such as ammeters and voltmeters, are calibrated to read the root mean square (rms) value of the alternating current or voltage. The rms value is a measure of the effective value of an AC waveform and is used as a standard measure in AC circuits.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
