This can cause the battery with the lower internal resistance to overheat and be damaged. To prevent this, it is important to ensure that the batteries have identical internal resistance.<\/p>\n<p>Option A is incorrect because the batteries can have different emfs as long as they have identical internal resistance. The emf of a battery is the voltage that it produces. The internal resistance of a battery is the resistance to the flow of current through the battery.<\/p>\n<p>Option B is incorrect because the batteries can have different makes as long as they have identical internal resistance. The make of a battery is the brand of the battery. The internal resistance of a battery is the resistance to the flow of current through the battery.<\/p>\n<p>Option C is incorrect because the batteries can have different ampere-hour capacities as long as they have identical internal resistance. The ampere-hour capacity of a battery is the amount of current that the battery can produce for a given period of time.
