How can we convert a moving coil galvanometer into a voltmeter? |
By introducing a low resistance in series By introducing a high resistance in series By introducing a high resistance in parallel By introducing a low resistance in parallel |
By introducing a high resistance in series |
Moving-coil galvanometer can be converted into a voltmeter by increasing its effective resistance by connecting a high resistance in series with the galvanometer. The series resistance protects the meter and increases the range of the meter. |
