A cell of emf `3.4 V` and internal resistance `3 Omega` is connected to an ammeter having resistance `2Omega` and to an external resistance of `100Omega`. When a voltmeter is connected across the `100 Omega` resistance, the ammeter reading is `0.04 A`. Find the voltage reading by the voltmeter and its resistance. Had the voltmeter been an ideal one what would have been its reading?

A cell has an emf of 3 volt and internal resistance 2Omega . It is connected to an ammeter having resistance 2Omega and to an external resistance of 100Omega . When a voltmeter is connected across the 100Omega . Resistance, the ammeter reading is 40 mA. The resistance of the voltmeter is

A voltmeter has a resistance of 50 Omega is connected across a cell of e.m.f. 2V and internal resistance 10 Omega . The reading of voltmeter is

The voltmeter reads 40 V across 60 Omega resistance. The resistance of voltmeter is. .

A battery of EMF 1.4 V and internal resistance 2Omega is connected to resistor of 100Omega resistance through an ammeter. The resistance of the ammeter is (4)/(3)Omega . A voltmeter is also connected to find potential difference across resistor. The ammeter reacds 0.02 A if resistance of voltmeter is 100x then x is

In Fig. 6.59 , when an ideal voltmetre is connected across 4000 Omega resistance, it reads 30 V . If the voltmeter is connected across 3000 Omega resistance, it will read
