Question

which of the the following statements is true about the resistances X, Y and Z for the given V - I graph?​

Answer 1

Explanation:

(d) is your answer.

since voltage will then current will increase and resistance will decrease

Answer 2

Option (1) X>Y>Z is the correct answer.

since we know R =V/I

So if voltage is higher than the current resistance will be higher. (X)

but if voltage is lower than the current then the resistance will be lower (Z).
