A) k is independent of A
B) \[K\propto {{A}^{-1}}\]
C) \[K\propto A\]
D) \[K\propto {{A}^{2}}\]
Correct Answer: C
Solution :
Resistance of wire \[R=\frac{\rho l}{A}\] Rate of flow of electrons K is equal to the current flowing in wire i.e., \[i\propto A\] also, \[i\propto \frac{1}{R}\propto A\] So, \[K\propto A\]You need to login to perform this action.
