RS Flipflop Truthtable for Q=1 and Q* = 0
So when we go for R = 1 and S = 0, why isn't the value of Q* = 0? I
  just don't get it.




When R = 1, it forces Q to be 0 (iirespective of nQ) and that puts a zero as an input on the other NOR gate. With S being zero on the other NOR gate input, nQ has to be 1. That's how it works.
