Not quite sure now. Using multimeters at college, I think the ampmeter was set to "10A" and the voltmeter on "20V"
How would this affect the readings?
Would this mean that I'd have to halve my readings of p.d. before putting them into the formula R=V/I to work out Resistance. If yes, then...
OK doing some physics coursework at the moment where I have to measure the resistivity of Constantan. Anyway, for those who don't know, the resistivity of constantan is 49x10^-8.
Anyway the formula for those who don't know for resistivity is...
RA/l
So anyway at length of 100cm, with a...
