Homework Statement



how will you convert a galvanometer of resistance 150 ohm giving a full scale deflection for a current of 3 milli ampere to a ammeter of range 0 to 6 ampere?a uniform rsistance wire of length 60cm and 2 ohm is given.find the length of the wire required?

Homework Equations



s = IgG/I-Ig

Should we connect a piece of the resistance wire in series or in parallel with the galvanometer? Why do you think so?
