Of the following graphs, the one that correctly represents the I-V characteristics of a Ohmic device is

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
According to Ohm.s law,
i.e., `V alpha I`
V = IR
`(V)/(I)=R` (constant)
Hence, the curve between V and I is straight line.
