A.c ammeteris constructed on the basis of heating effect of electric current.since the heat produce varies as the square of current (and not directly with current)
the division marked on are not equally spaced
the division marked on are not equally spaced

The divisions marked on the scale of an A.C ammeter are not equally spaced because an ammeter works on the principle of heating effect produced from the electric current.
• As heat produced varies as square of current thus the divisions are not equally spaced.
• An A.C ammeter is used to measure the alternating current flowing through the circuit.
