Question

Suppose in an experiment, data is collected of the variation of current with

resistance R. Next a plot of R vs I

-1 is made. How does one determine the

value of V from that graph? (Explain your answer using an appropriate

expression.)

Answer 1

Given,

Resistance in the circuit = R

The value of current = I

So, potential in the circuit$(V)= IR$

Hence, the variation in of current with respect to the resistance,

$I\propto \frac{1}{R}$

Hence, we can say that,
