so
but since we are in QII (where x is negative and y is positive) we have to add 180 to this number to get a direction of 165.5 degrees
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
