Two resistors having equal resistances are joined in series and a current is passed through the combination. Neglect any variation in resistance as the temperature changes. In a given time interval (a) Equal amount of thermal energy must be produced in the resistors(b) Unequal amounts of thermal energy may be produced (c) The temperature must rise equally in the resistors (d) The temperature must rise unequally in the resistors
