Problem
A student recorded the following readings while testing a wire: V (in V) : 1.5 , 3.0 , 4.5 I (in A) : 0.30 , 0.60 , 0.90 Calculate the average resistance of the wire from these readings. a) b) c) d)Intuitive explanation
This problem tests Ohm's law and your ability to handle experimental data. The key insight is that resistance should be constant for an ohmic conductor, so you'll calculate for each pair of readings, then average them to account for small measurement uncertainties. This gives you a more reliable result than using just one data point.
