Two cells A and B of emf 1.3 V and 1.5V respectively are arranged as shown in figure. The voltmeter reds 1.45V . The voltmeter is assumed to be ideal. Then

Two cells A andB ofEMF 1.3V and 1.5V respectively are arranged as shown in figure-3 .322. The voltmeter connected in circuit is ideal and it reads 1.45V. Which cell has the higher internal resistance and how many times that of the other?

An ammeter A, a voltmeter V and a resistance R are connected as shown in the figure. If the voltmeter reading is 1.6V and the ammeter reading is 0.4 A, then R is

An ammeter A, a voltmeter V and a resistance R are connected as shown in the figure. If the voltmeter reading is 1.6V and the ammeter reading is 0.4 A, then R is

An ideal voltmeter V and ideal ammeter A are connected in a circuit as shown in the figure. If the reading of the voltmeter is 32 V, the reading of ammeter will be

When key K is open in a circuit as shown in figure, an ideal voltmeter reads 1.53 V. If key is closed then ideal ammeter reads 1A and voltmeter reads 1.03 V. Then EMF of cell and external resistance R are respectively

The emf E and internal resistance r of the cell shown in fig. are 4.3 V and 1 ohm respectively. The resistances of ammeter A and voltmeter V are 2Omega and 200Omega respectively. Then, the readings in the ammeter and voltmeter
