                                    A battery of emf 10V and internal resistance 0.5 ohm is to be charged by a battery charger which supplies 110V dc. The resistance that must be connected in series with the battery to limit charging current to 5A is R and terminal voltage across the battery during charging is Vt. Then R and Vt are respectively? |
