A dry cell of emf 1.5 V and internal resistance 0.10 Ω is connected across a resistor in series with a very low resistance ammeter. When the circuit is switched on A series battery by 6 lead accumulators each of emf 2.0 V and internal resistance 0.5Ω is charged by a 20V d.c. supply circuit in order to limit the current to 1A. Calculate the power supplied by the source and the fraction of energy stored in the battery in 15 min. What series resistance should be used in the charging
