    The addition if the little circle makes it a NOT and an OR together so it is NOR

    I got something different. I used the formula Np/Ns * Vs to get Vp and I compared it to the primary voltages listed in the table. Thus I got the voltage was 20,000 for the primary and for D 50 for the primary. I am not sure this is correct though.
    For D everything was correct expect the output voltage shouldn't have been 1000 but 200 instead. As if you checked with the others ratio between the two matched the output expect for D.

    I don't know anymore. It seems I was terrible at this exam which does not reflect any of my mock results .

    Dont worry - how many marks was this question anyway?

    Yes because 0.447... to 1.d.p is 0.4m/s.
    Did it ask for 1 d.p. In that case im screwed

    Not at all. As you long as you rounded it correctly you will get the marks.

    Well it's an OR gate (curved bit) with the dot at the end which means add a NOT to it afterwards, hence making a NOR.

    A NAND would look like this but the curved bit would be flat.
    Was the end bit curved for the last logic gate flat? In that case i got it wrong, shouldve realised the detail . I felt like all i had to rush all the exams for the 4,5,6 modules, so i didnt have any time to check over

    Ah ok, thats a bit of a relief atleast, especially because i messed up the first and last 6 markers

    I think it was curved

    I agree - I rushed the paper too
