" Lead accumulator "

Power from a 64 V d.c. supply goes to charge a battery of 8lead accumulators each of emf 2.0V and internal resistance 1//8Omega . The charging current also runs an electric motor placed in series with the battery. If the resistance of the windings of the motor is 7.0Omega and the steady supply current is 3.5A. obtain.

A series battery of 6 lead accumulators each of emf 2.0V and internal resistance 0.50Omega is charged by a 10V d.c. supply. What series resistance should the used in the charging circuits in order to limit the current to 8.0A? Using the required resistor, obtain (a) the power supplied by the d.c. source (b) the power supplied by the d.c. energy stored in the battery in 15min.

A series battery of 10 lead accumulators each of emf 2V and internal resistance 0.25ohm is charged by a 220V d.c. mains. To limit the charging current a resistance of 47.5 ohm is used in series in the charging circuit. What is (a) the power supplied by the mains and (b) power dissipated as heat? Accout for the difference of power in (a) and (b).

A car battery Is made of lead plate dipping Into sulphuric acid (Lead Accumulator). It can be recharged. When the battery is used a reaction takes place. Identify the change to this reaction when the battery is recharged and represent the reactions at the anode of the cell.

A series battery of 6 lead accumulators, each of emf 2.0V and internal resistance 0.25 Omega is charged by a 230V d.c. mains to limit the charging current, a series resistance of 53Omega is used in the charging circuit. What is (i) power supplied by the mains (ii) power dissipated as heat? Account for the difference in the two cases.
