Question

the table given below show the resistivity of three material x,y and z
x resistivity-3*10^-9
y resistivity-11.1*10^-6
z resistivity-18*10^-17
(a) which the best conductor
(B) which is the best insulator
arrange the sample in increasing order of conductivity

Answer 1

Answer:

here is your answer -

Explanation:

I am doing c here first so as better for you to understand .

c) since resistivity is always in same order as it written here negative need not be considered but you have to write it so

Z<X<Y

a) as above bes conductor will be Y

b) as above best insulator will be Z

Answer 2

Answer:a] y is the best conductor due to low resistivity

b] z is best insulator
