resistance

Physics, why do you boggle my mind. Why do we need a variable resistor?

Scratch that, Steph N told me we didn't need to (or at least I didn't, because my drawing didn't feature it). I SHALL TYPE IT UP NOW, WITHIN 30 MINUTES OR SO, AND THEN STUDY IT. AND THEN I'LL FINISH TUTOR HW...

I feel so happy, thanks Steph <3 :D

WOOHOO!
