As torque/weight ratio is more in PMMC instruments, the accuracy is very high in these instruments. PMMC instruments are used in rectifier type instruments, hence these are also equally accurate.
Moving iron instruments has the least accuracy among all the given instruments.
The order of accuracy in descending order
PMMC > Electrodynamometer > Moving Iron
