A galvanometer reads 5⋅0V at full scale deflection and is graded according to its resistance per volt at full scale deflection as 5000ΩV−1. (i) How will you convert it into a voltmeter that reads 20V at full scale deflection? (ii) Will it still be graded 5000ΩV−1? (iii) Will you prefer this voltmeter to one that is graded 2000ΩV−1?
