Homework Statement
Transmission line is designed so it has selfinductance, L = 7.0x10^-7 Hm^-1 & signal speed 70% of c
Find characteristic impedance
Homework Equations
Z = √L0/C0 Ω
also
v = 1/ √L0C0
The Attempt at a Solution
So
L = 7.0x10^-7 Hm^-1
v = 0.7c (c = 3x10^8 ms^-1)
7(3x10^8)/10 = 1/√7.0 * C0
so
C0 = √((10(7.0x10^-7))/(7*3x10^8))
C0 = √ 3.33x10^-15
C0 = 5.77x10^-8 F
Z = √L0/C0
Z = √7.0x10^-7/5.77x10^-8
Z = 3.4 Ω
Which isn't in the park as far as expected result goes, so AGAIN, please could you show me where I went wrong.
