Question

alternating current measuring devices have linear or non linear scale, why​

Answer 1

These meters have linear scales. Because the magnetic field is polarised, the meter needle acts in opposite directions for each direction of current. ... This type of meter responds to both direct and alternating currents (as opposed to the moving-coil ammeter, which works on direct current only).

Answer 2

These meters have linear scales. Because the magnetic field is polarised, the meter needle acts in opposite directions for each direction of current. ... This type of meter responds to both direct and alternating currents (as opposed to the moving-coil ammeter, which works on direct current only).
