Conversion of Galvanometer in to Voltmeter
The purpose of voltmeter is to measure the voltage. If we want to convert a Galvanometer into a voltmeter then a high resistance is connected in series with the Galvanometer. As far as the value of the resistance, it is related with the range of voltmeter. For making the reading of voltmeter more accurate the large resistance should be connected. It should be kept into consideration that voltmeter is connected in parallel to the resistor for measuring potential Difference.
