find the voltage help?

for number 18, you do V IxR....10uA would be 0.01 so you'd do 50/0.01 and that gives you the voltage of 0.5v?

am I doing that right?

right answer - bit of a strange method though imo.
50/0.01 = 500

I think just have gone (10x10^-6) x (50x10³) = 500x10^-3
=0.5

so if I had 20uA and a 80k resister id do...
20x10(-6) x 80x10(3) and get 1.6?
