Hi________§ dear
generally we try to make resistance which have high resistivity
we made resistance coil by maganin bcz
>the resistivity of manganin is very high and any desired resistance can be made with convenient dimensions of the material.
>the manganin is less sensitive by temperature ,i.e when temperature ise very then resistance of maganin is not very, that is the main advantage of the maganin.
hope it u
