What do you understand by figure of merit ?

Answer»

SOLUTION :Figure of merit is defined as the current required per division of deflection derivation
`K = (1)/(theta)`, SI unit A/div
in observation for half deflection METHOD
`i_(G) = Ktheta, i_(g) = (E )/(R+G)`
`k=(1)/(theta) [ (E )/(R+G)]`
It enables us to FIND current required for full scale deflection.
