To convert a galvanometer into a voltmeter one should connect a:
✓ Correct answer: a) high resistance in series with galvanometer
ExplanationA voltmeter is an instrument used to measure the electrical potential difference between two points in an electrical circuit.Analog voltmeters shift the pointer over a scale in relation to the voltage of the circuit.The fundamental theory of the voltmeter is that it must be wired parallel to the voltage that we want to calculate.The parallel connection is used as the voltmeter is built in such a way that it has a very high resistance value.In order to convert a galvanometer to a voltmeter, a high resistance is connected to it in series.Since voltmeter can measure the potential voltage more accurately only with the help of high resistance.
