Question

15. The following table gives the resistivity of three samples.

Sample A B C

Resistivity 1.6 x 10-8 Ωm 5.2 x 10-8 Ωm 100 x 10-6 Ωm

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

why ?​

Answer 1

Answer:

100×10-6ohm m is suitable for heating elements of electrical appliances .because when an element has low resistance it can generate more energy
