A galvanometer of resistance G is converted into a voltmeter to measure upto V volts by connecting a resistance R_1 in series with the coil. If a resistance R_2 s connected in series with it then it can measure upto V/2 volts Find the resistance R, in terms of R_1 and R_2 required to convert it into a voltmeter that can read upto 2V volts.

A voltmeter of resistance R is to be used to meaure a voltage 100 times as large as it can measure without an additional resistance in seires. How alrge a resistance is to be used in series with the meter?

The resistance of ammeter is very high as compared to voltmeter .

By mistake a voltmeter is connected in series and an ammeter is connected in parallel, with a resistance in an electrical circuit. What will happen to the intruments?
