A 5V battery with internal resistance 2Omega and a 2V battery with internal resistance 1Omega are connected to a 10Omega resistor as shown in the figure.

A battery of emf 15 V and internal resistance of 4Omega is connected to a resistor. If the current in the circuit is 2A and the circuit is closed. Resistance of the resistor and terminal voltage of the battery will be

A cell of e.m.f. 2V and internal resistance 0.5Omega is connected across a resistor R. The current that flows is same as that, when a cell of e.m.f. 1.5V and internal resistance 0.3Omega is connected across the same resistor. Then

A cell of e.m.f. 2 V and internal resistance 1.2 Omega is connected to an ammeter of resistance 0.8 Omega and two resistors of 4.5 Omega and 9 Omega as shown in Fig. find : the potential difference across the 4.5 Omega resistor.

A battery of internal resistance 3Omega is connected to 20Omega resistor and the potential difference across the resistor is 10V. If another resistor 30Omega is connected in series with the first resistor and battery is again connectecl to the combination, then calculate the e.m.f and terminal potential difference across the combination..

A battery of emf 1.4V and interna! resistance 2Omega is connected to a resistor of 100Omega resistance through an ammeter. The resistance of ammeter is 4/3Omega a voltmeter has also been connected to find the potential difference across the resistor. The voltmeter reads 1.10V. What is the error in the reading ?
