I suspect the OP has not come back because no one gave him an instant answer and told him how to do it although I could be wrong

Mech you're such a cynic. The gadgie might be busy working the answer out

Can’t think why, he’s got both Markies and my answers.
You can’t get better proof than two different calculations with the same answer.
But he really should do his own homework.

Thanks for all the help guys this question has blown my brain to bits hahaha i get all of the working out but how did u know how to do it

(Rc+Rs)/Rs=N
(4+0.005)/0.005=801
Ic = Is/N
50/801 = 0.0624
0.0624 x 1000 = 62.4mA
