Question

5. The following table gives the resistivity of three samples:



Sample A B C

Resistivity 1.6x 10-5
Wm 5.2 x 10-5Wm
100 x10-4Wm

Which of them is suitable for heating elements of electrical appliances and why?

​

Answer 1

Answer:

Sample 3 because it's resistivity is higher than other than 2 samples so it will resist more amount of electricity .
