Ok thank you for your help

it says in my textbook that the threshold P.d. of a silicon diode is around 0.7V so it that where it comes from and is that something that i would have to assume then? so would that mean the P.d. in the diode (between b and c) is 0.7V, would that mean that the P.d. of R1 is 5.3V and the current...

I haven't been given a datasheet, I am just wondering if there is a way for me to find the resistance of the diode, also would it be possible for the resistance of the diode to be negative? Because I am not sure if i have just messed up my calculations or if it is actually possible.

I've tried doing it but i haven't been able to find the resistance of the diode.
