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.
