Question

QUESTION
On what factors does the resistance of a conductor depend?
Will current flow more easily through a thick wire or a thin wire of
same material, when connected to the same source? Why?
Let the resistance of an electrical component remains constant w
the potential difference across the two ends of the component decrea
to half of its former value. What change will occur in the current thro
it?
Why are coils of electric toastets and electric irons made of an a
rather than a pure metal?
Use the data in Table 12.2 to answer the following -
(a) Which among iron and mercury is a better conductor?
(b) Which material is the best conductor?​

Answer 1

Answer:

COPPER HAS THE LEAST RESISTANCE...

I THINK IRON AND MERCURY BOTH ARE OK OK NOT THE BEST

Answer 2

Answer:

1. factors on which resistance depends upon is:

area of cross-section,from which material is wire made
