The current through a coil and the corresponding potential difference across it were recorded as:
(0.10 A, 0.62 V), (0.30 A, 1.88 V), (0.50 A, 3.10 V)
(a) Using the first and last readings, find the resistance of the coil.
(b) In one sentence, state why selecting readings that are far apart yields a better estimate of resistance than using two closely spaced readings.
