    For the paper below, in question 17bii, i know that it gives you the correct answer but it is not on the mark scheme with the 5 methods that they have put, so could you just do the R=V/I where V=2.6V and I=5550A?

    Depends really. You need to ask a teacher because your answer would only be accepted in one of 5 of those methods they put in the mark scheme.

    "Examiners should also be prepared to award zero marks if the candidate’s response is not worthy of credit according to the mark scheme."

    "Mark schemes should be applied positively. Candidates must be rewarded for what they have shown they can do rather than penalised for omissions."

    No. The mark scheme is explicit that one of the five methods is used.

    Clearly the question is aimed at a basic knowledge of the time-constant relationship between the capacitance and discharge path resistance.

    Using ohms law is unacceptable.
