Question

in VI graph for 2 wires a and b are shown in the figure if both the wires are of same length and same thickness which of the wires are made of high resistivity ​

Answer 1

Answer:

a wire has high resistivity which has smaller slope

Answer 2

Answer:

Hey there

Explanation:

So this is pretty simple, if you know the formula for finding resistance which is R=V/I so , if the potential is more then it will have greater resistance eg:

Taking V=10 and I=5 we get 2 and taking V=5 and I=10 we get 0.5

So, A has greater resistance than B
