Two identical cells each of emf 1.5 V are connected in series across a 10`Omega` resistance.An ideal voltmeter connected across 10`Omega` resistance reads 1.5 V.The internal resistance of each cell is ________`Omega`.

In the given circuit, an ideal voltmeter connected across the 10Omega resistance reads 2V. The internal resistance r, of each cell is:

A cell which has an emf 1.5 V is connection series with an external resistance of 10Omega . If the potential difference across the cell is 1.25 V, then the internal resistance of the cell is ("in" Omega)

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

A cell has an emf 1.5V. When connected across an external resistance of 2Omega , the terminal potential difference falls to 1.0V. The internal resistance of the cell is:

If 8 cells having an emf of 1.5 V are connected in series across a load having resistance of 10 Omega . What is the current drawn by the load ? Assume internal resistance of all be 0.5 Omega .

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

In the circuit shown, reading of the voltmeter connected across 400 Omega resistance is 60 V. If it is connected across 300 Omega resistance then reading in volt will be

In a mixed grouping of identical cells, five rows are connected in parallel and each row contains 10 cells. This combination sends a current I through an external resistance of 20Omega. if the emf and internal resistance of each cell is 1.5 V and 1 Omega, respectively then find the value of I.

A battery of emf 2V and internal resistance 0.5(Omega) is connected across a resistance in 1 second?
