Question

i) Observe the following table. Which of the material can be used for
transmission of electricity, heating material and insulator, and why?
Material Resistivity (Am)
A
1.62 x 10-8
B
100 x 10-6
C
1*10-8​

Answer 1

Answer:

The correct answer if this question is $A$ →  $1. 62$ × $10^{-8}$ → Copper

Step-by-step explanation:

Given - The material can be used for transmission of electricity, heating material and insulator .

To Find - Write the material which is used for transmission of electricity, heating material and insulator .

Copper may be used to transmit electricity because of its low resistivity.

$B$ → $100$ × $10^{-6}$ → Nichrome

Nichrome is a high-resistivity alloy containing Ni, Cu, Mn, and Fe that can be utilised as a heating material. As a result, it's best used for heating. Even at high temperatures, nichrome does not burn easily.

$C$ → $1$ × $10^{10}$

This can be used as an insulator since it does not allow heat or electricity to easily pass through it, therefore stopping the flow of electricity and preventing electric shocks.
