I am beginning to form a suspicion.
No more than a suspicion at the moment, but I admit the feeling is growing that I was perhaps incorrect to state – in my Physics Practical exam – that we had been provided with an output voltage of 4000V.
Why, you may ask innocently? Well, when I stop and ponder my result, it does start to sound like an awfully large number of volts. Those signs, for example: “Warning! High Voltage! Danger of Death!”. They refer to figures like 4000V, don’t they? It seems a little… excessive… for Edexcel to insist we work with such a number. How about another number? Such as, oh I dunno, 4V?
There’s another piece of evidence with suggests to my mind that perhaps that is closer to the truth: the large 4 on the setting of the power supply.
Hmm… 4, and 4000. There’s a link there, isn’t there? Why yes, of course! The second is merely one thousand times larger than the first. Almost as if, if I may dare to be so bold, a unit may have gone awry. For the non-Physicists amongst you, consider than a metre is made out of one thousand millimetres. Aha!
Hopefully, some nice examiner will merely dock a point for a unit somewhere, rather than chuckle and then burn the paper
Don’t worry, I don’t actually think it went too badly, folks just the usual twists and turns which accompany the now-slain beast of the Physics Practical. Fire in the disco!
