Homework Statement



A range of metallic alloys are tested for electrical conductivity and give the following results for identically sized samples.

25% copper with 75% tin gave a reading of 0.0071 Ohms
65% copper with 35% cadmium gave a reading of 0.0049 Ohms
40% copper with 40% tin and 20% cadmium gave a reading of 0.0060 Ohms

Using matrix algebra, determine the resistance of an equally sized sample for each of the pure metals –

(a) Copper
(b) Tin
(c) Cadmium

The Attempt at a Solution



I was hoping someone could shine some light on this!

Can you write equations that describe the three measurement situations?
