Ok, first of all thanks for the help and advise, secondly, I think i must be missing something simple because if assuming no drop across my diode I can't find I2 using this method as I have no value to fit in the equation
i.e. Vd = 0, so I2 = Vd/R2 is a fail
Vr = Vs so 10v (no drop)
It= Vr/R1 or 10/10000 = 1ma
Id = It - I2 which fails because I have no values for Id or I2 this is where I am stuck, basic current division in a 2 resistor parallel circuit uses I2 = (It)(R1)/(R1+R2), giving .9ma
This would then fit the equation giving Id as .1ma, the only trouble is the answer I am given is .3ma, can anyone point out where I have gone wrong?
Thanks in advance
