Answer:
The current in the filament is 0.81 A
Explanation:
Given :
Diameter of wire
m
Diameter of filament
m
Current density 
From the formula of current density,

Where
area =
Current in the filament is given by,

Area of filament is given by 
Put value of A in above equation,

A
Therefore, current in the filament is 0.81 A
That if you see them in a dogram they are not like a solid state of matter and not like a glass they are close together but not in rows
Is this what you mean I’m not sure but that’s what I seee
Answer:
The student is wrong
Explanation:
