The figure below represents a section of a circular conductor of nonuniform diameter carrying a current of
I= 5.70 A . The radius of cross-section
A_(1) is
r_(1)=0.330cm.
(a) What is the magnitude of the current density across
A_(1) ?
(A)/(m^(2))
The radius
r_(2) at
A_(2) is larger than the radius
r_(1) at
A_(1).
(b) Is the current at
A_(2) larger, smaller, or the same?
The current is larger.
The current is smaller.
The current is the same.
(c) Is the current density at
A_(2) larger, smaller, or the same?
The current density is larger.
The current density is smaller.
The current density is the same.
Assume
A_(2)=3A_(1).
(d) Specify the radius at
A_(2).
mm
(e) Specify the current at
A_(2).
A
(f) Specify the current density at
A_(2).
(A)/(m^(2))
