SUMMARY
The characteristic impedance of a transmission line can be calculated using the formula Z = √(L0/C0), where L0 is the self-inductance and C0 is the capacitance per unit length. In this discussion, L was given as 7.0x10^-7 Hm^-1 and the signal speed was 70% of the speed of light (c = 3x10^8 ms^-1). The correct calculation for C0 yielded 5.77x10^-8 F, leading to a characteristic impedance Z of 3.4 Ω after resolving an initial calculation error involving squaring. The final result aligns with the expected theoretical framework.
