The following question for problem 1 to 5:
A solid cylindrical wire of radius a carries current I in the positive direction. The wire conductivity is radially dependent and is given by p = p S/m, where p is a constant. The electric field intensity, constant throughout the wire volume, is given by E = Ee aV/m (unit vectors: y a).
1. Find J in terms of E and p.
A. J = EaA/m
B. J = Ep aA/m
C. J = Eop aA/m
D. J = EaA/m
E. None of the above
2. Find E in terms of a.
A. E = 1/2aV/m
B. E = 3√(1/2a)V/m
C. E = 5√(1/2a)V/m
D. E = √(1/2a)V/m
E. E = 2√(1/2a)V/m
3. Express J in terms of I and other parameters, excluding E.
A. J = Ip/2aA/m
B. J = 3Ip/2aA/m
C. J = 5√(1/2a)A/m
D. J = √(1/2a)A/m
E. J = 2√(1/2a)A/m
Using your problem 3 result, find H inside and outside the wire (a unit).
A. Inside: H = I/2aA/m, Outside: H = Ip/2aA/m
B. Outside: H = √(1/2a)A/m, Inside: H = I/2aA/m
C. Inside: H = I/(2a)A/m, Outside: H = 2I/2aA/m
D. Inside: H = 2√(1/2a)A/m, Outside: H = 3I/(2a)A/m
E. None of the above
