Hey everyone,

Could someone please shine some light on this question, I'm not sure I fully understand how it's worded?

Chris.

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
