A voltmeter reads 5.0 volt at full scale deflection and is graded according to its resistance per volt at full-scale deflection as 5000ΩV−1. How will you convert it into a voltmeter that reads 20 V at full-scale deflection? Will it still be graded as 5000ΩV−1? Will you prefer this voltmeter to one that is graded 2000ΩV−1?
