Two identical resistors each of 8Ω are connected to a battery. Without doing any calculation, choose the arrangement that will give a total resistance less than 8Ω.
(a) Both arrangements produce an equivalent resistance of 8Ω
(b) Parallel connection of the two resistors
(c) Series connection of the two resistors
(d) It is impossible to obtain a resistance lower than 8Ω using the two 8Ω resistors
