![A galvanometer acting as a voltmeter will have [2004, 2002] (a) a low resistance in series with its coil. (b) a high resistance in parallel with its coil (c) a high resistance in series with its coil (d) a low resistance in parallel with its coil Ans: (c) Solution: A galvanometer can be converted into a voltmeter by connecting the high ressistance in series with the galvanometer so that only a small amount of current passes through i](https://4.bp.blogspot.com/-O3EpVMWcoKw/WxY6-6I4--I/AAAAAAAAB2s/KzC0FqUQtkMdw7VzT6oOR_8vbZO6EJc-ACK4BGAYYCw/w100/nth.png)
