‘PMMC instrument is not suitable to measure AC quantity’. State the reason.
‘PMMC instrument is not suitable to measure AC quantity’. State the reason.
Last answer:
The direction of force exerted on moving coil depends on the direction of current flowing through moving coil. If the direction of magnetic field is kept constant, it produces unidirectional torque if the current is ... on the coil in one cycle to zero. Hence the meter cannot read A.C. quantities.
