If E denotes electric field in a uniform conductor, I corresponding current through it, v d -drift velocity of electrons and P denotes thermal power produced in the conductor, then which of the following graph is incorrect -
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
E = 
= 
= 
= 
= nev d ρ
v d ∝ E straight line
P = I 2 R = 
× R = 
⇒ P ∝ E 2 (Parabola)
P ∝ I 2 Parabola
