The galvanometer shown in the figure reads 3A, while the ideal voltmeter reads 24 volt. The value of `R = 7 Omega`. The galvanometer resistance is :

In the combination shown in the figure, the ideal voltmeter reading will be

The voltmeter shown in the figure reads 10V across 40 omega . The resistance of voltmeter is

The voltmeter V in the figure. Reads 117V and the ammeter A reads 0*13A . The resistance of the voltmeter is 9000Omega and the resistance of ammeter is 0*015Omega . Compute (i) the resistance R, (ii) the power input to R.

A galvanometer of resistance R ohm when used as a voltmeter can read V volts (maximum) A multiplier is connected in series with the Galvanometer so that it is made a voltmeter that can read (NV) volts, (N>1). The value of the multiplier resistance (R_m) in ohms is

The voltmeter in figure has a resistance of 200 Omega . The reading of voltmeter is

How will you convert galvanometer which needs 50 mA for full scale deflection into a voltmeter reading upto 2.5 volts ? The resistance of the galvanometer is 10 ohms.

A circuit is shown in the figure. The ratio of readings of ideal voltmeter to reading of ideal ammeter is

The voltmeter shown in figure reads 18V across the 50(Omega) resistor. Find the resistance of the voltmeter.
