Physics SPA was *surprisingly* easy. Hopefully I'll get full marks for that, although I was really really close to failing it. We were required to determine the relationship between 1/V (reciprocal of voltage) and R (the resistance) in a series circuit. No contextual knowledge required (: Almost every procedure and required sections were already printed in the question sheet.
Anyway, there was one part where I nearly got tricked (poor Clement). We were given 3 resistors of different resistance, and we were supposed to observe how the reading on the voltmeter varies with the total resistance. There was one step that was particularly confusing: The results can be obtained by connecting the resistors SINGLY *AND* by connecting them in series. The first time I did the experiment I really did miss out the AND keyword. But I realized that Mr Steven Su was observing me for like close to 5 minutes, so I started to think that something was really wrong.
TURNED OUT THAT I WAS LUCKY xD Once I started connecting them in combinations, Mr Steven Su walked away so I thought I was already doing the right thing ;D YONGJIE you couldn't be more careless than that! Next time pay attention to the details!
Anyway, for those who are interested, my readings:
Gradient: 1.2 x 10-4
Resistance of voltmeter: 2100 Ω (to 2 s.f.)
On another note, I have completed yet another poster :D But not now. It wasn't actually my work, so I don't want to post it.
Anyway, to any boarding councillor who is reading this, jiayou for NDD :D
