Q. To convert a galvanometer into a voltmeter, a ______ resistance is connected in _____.

To convert a galvanometer into a voltmeter, one should connect a

A glavanometer of 50 Omega resistance has 25 divisions. A current of 4xx10^(-4) A gives a deflection of one division. To convert this galvanometer into a voltmeter having a range of 25 V , it should be connected with a resistance of

The maximum current in a galvanometer can be 10 mA. Its resistance is 10 Omega . To convert it into an ammeter of 1 A, what resistance should be connected in parallel with galvanometer (in 10^(-1)Omega) ?

To convert galvanometer into ammeter which one of the following is connected with the coil:

The conversion of a moving coil galvanometer into a voltmeter is done by

A galvanometer has a current range of 15mA and voltage range of 750mv. To convert this galvanometer into an ammeter of range 25A, the sunt resistance required is nearly

A galvanometer having internal resistance 10 Omega required 0.01 A for a full scale deflection. To convert this galvanometer to a voltmeter of full scale deflection at 120 V, we need to connect a resistance of

The deflection of a galvanometer falls to 1//10^(th) when a resistance of 5Omega is connected in parallel with it. If an additional resistance of 2Omega is connected in parallel to the galvanometer, the deflection is

In the circuit shows in Fig. 6.42 , resistors X and Y , each with resistance R , are connected to a 6 V battery of negligible internal resistance. A voltmeter, also of resistance R , is connected across Y . What is the reading of the voltmeter?

(a) Briefly explain how a galvanometer is converted into a voltmeter. (b) A voltmeter of a certain range is constructed by connecting a resistance of 980 Omega in series with a galvanometer. When the resistance of 470 Omega is connected in series, the range gets halved. Find the resistance of the galvanometer.
