Question

3. A copper wire of mass 20 g carries a current of 6.023
A: What fraction of the total number of free elec-
trons present in copper wire flows through the cross-
section of the copper wire in 2 s?
(gram atomic weight of copper = 63.5 g)​

Answer 1

Answer:

A copper wire of mass 20 g carries a current of 6.023

A: What fraction of the total number of free elec-

trons present in copper wire flows through the cross-

section of the copper wire in 2 s.

(gram atomic weight of copper = 63.5 g)

Explanation:

calculate the des isdance of Ikm

long copper wire of radius 1 mm

(Resistivity of copper = 1 F2 x 10 8 nm
