Question

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

Answer 1

HELLO DEAR,

GIVEN:- Calculate the value of R1 and R2 by finding the

slopes from the given I-V graph.

SOLUTION:-

we know that , V = Rl

R = V/l

where V = voltage

R = resistance of wire

l = electric current

According to graph,

$\bold{R_1 = \frac{V_1}{I_1}}$

$\bold{R_1 = \frac{26}{0.8}}$

R1 = 32.5 Ω

And R2,

$\bold{R_2 = \frac{V_2}{I_2}}$

$\bold{R_1 = \frac{12}{0.8}}$

R2 = 15 Ω

Therefore, R1 = 32.5 Ω and R2 = 15 Ω

THANKS.

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
