A student carries out an experiment and plots the `V-I` graphs of three samples of nichrome wire with resistances `R_1,R_2 and R_3` respectively, (Fig. 3.41). Which of the following is true ?

A

`R_1 = R_2 = R_3`

B

`R_1 gt R_2 gt R_3`

C

`R_3 gt R_2 gt R_1`

D

`R_2 gt R_3 gt R_1`

Text Solution

Verified by Experts

The correct Answer is:
C
For a given voltage `(V),I_1 gt I_2 gt I_3`. Since `R = (V)/(I), R_3 gt R_2 gt R_1`.
