Question

PLEASE HELP ITS VERY URGENT

Study the I-V graph for four conductors A, B, C and D having resistance Ra, Rb, Rc, and Rd respectively and answer the following questions :-

1) Which one of these is the best conductor?

2) If all the conductors are of the same length and same material, which is the thickest ?

3) If all the conductors are of same thickness and of same material, which is the longest?

4) If the dimensions of the conductors are identical, but their materials are different which one would you use as (I) resistance wire (ii) connecting wire ?
