Solution of EE3604 HW #2
[Solution]:
(a) Choose a point P1(0,0,4), which has the same z = 4 coordinate as the point P, on the current filament,
thus
1 = P(2,3,4) P1(0,0,4) = (2ax + 3ay)/13
H1 = (I/22)az 1 = (810-3/26)(-3ax + 2ay) = -0.2938ax + 0.1959ay mA
EE3604 HW #1 Solution
[Solution]:
FB = l EA = [l 2/20(2y0)] ay = 0.127 ay mN/m
FA = l EB = -[l 2/20(2y0)] ay = -0.127 ay mN/m
[Solution]:
FB = S EA =(S 2/20) az = 0.565 az mN/m2
FA = l EB = -(S 2/20) az = -0.565 az mN/m2
[Solution]:
E = /0 = Ez/z =15z2/0
Solution of EE3604 HW #4
[Solution]:
[Solution]:
After the switch is closed at t = 0, a voltage wave V1- propagating to the left is generated. The total voltage across
RL becomes V0 + V1-, which equals to I1- RL = -(V1-/Z0)Z0 = - V1-, i.e., V0 + V1- = - V
