    Battery internal resistance question

    12. The internal resistance of a cell remains constant irrespective of the load current delivered by the cell.
    Your Answer: False
    Correct Answer: True

    Would this not be effected by the temperature as a direct result of the discharge?

    steady state / normal operating conditions this would be true.

    Temperature changes would affect the internal resistance weather external or internal IMHO but, I think this question is too vague and needs additional information but I would answer "True" since the question does not consider external temperature or internal temperature or temperature rise.

    Agree. Battery impedance is dependent on temperature, its state of charge, and the load frequency. Reading the question carefully, the "best answer" would be true.
