Answer:
The value is
Explanation:
From the question we are told that
The length of the wire is
The current density is
The conductivity is
Generally conductivity is mathematically represented as
Here R is the resistance which is mathematically represented as
Here I is the current which is mathematically represented as
So
And
=>
=>
=>
=>
Answer:
Decrease
Explanation:
I = Current = 3.7 A
e = Charge of electron =
n = Conduction electron density in copper =
= Drift velocity of electrons
r = Radius = 1.23 mm
Current is given by
The drift speed of the electrons is
From the equation we can see the following
So, if the number of conduction electrons per atom is higher than that of copper the drift velocity will decrease.
