95. A battery of four cells in series, each having an e.m.f. of 1.4 V and an internal resistance of 2 Ω is to be used to charge a small 2 V accumulator of negligible internal resistance. What is the charging current?
13
In the above question the internal resistance of the source is
14
What resistance R is required to charge a series battery of 12 lead accumulators, each of emf 2 V and internal resistance 1/24 Ω, from 240 V d.c. mains, if the charging current is not to exceed 3 A?
15
Six 1.1 V cells with internal resistance 3.0 Ω each are connected in three parallel branches of two cells each. If the resistance of external circuit is 2.0 Ω, then the current is
16
To get maximum current in a resistance of 3 ohm, one can use n rows of m cells (connected in series) connected in parallel. If the total number of cells is 24 and the internal resistance of a cell is 0.5 ohm, then
17
39. A current from a 50 V battery having an internal resistance of 4 Ω liberates total rate of heat 1.5 kJ/min upon passing current through a wire spiral (resistance coil). The resistance of the wire is
18
A 50 volt battery is connected across a 10 ohm resistor. The current is 4.5 ampere. The internal resistance of the battery is
19
All the voltmeters in figure are identical. The emf of the battery is 5 V and its internal resistance is negligible. The voltmeter V1 reads 2 V. Then readings of voltmeters V2 and V3 are respectively
20
An ammeter having a resistance of 1000 Ω gives full deflection for 10 µA. What should be the shunt resistance so that 10 mA gives full deflection?
