Question

Calculate the value of R1 and R2 by finding the slopes from the given I-V graph​

Answer 1

Explanation:

Using the relation [R=V/I] ,  which is inverse of the tangent of the given graph.  

As tangent of first is greater than second which is further greater than third, the order of resistance will be [R3>R2>

please mark as brilliant

Answer 2

Given  :   I-V graph​

To Find :  the value of R₁ and R₂

Solution:

Current  = Voltage / Resistance

=> I = V/ R

=> R = V/I

R₁   approx  V  = 15    I   = 0.4

=> R₁ = 15/(0.4)  = 37.5  Ω

R₂   approx  V  = 5    I   = 0.3

=> R₁ =  5/(0.3)  = 16.67   Ω
