236. The impedance total (ZO) of a transmission line can be calculated by ZO = √L/C when L and C are known. When a section of transmission line contains 250 microhenries of L and 1000 picofarads of C, its impedance total (ZO) will be:
The characteristic impedance is calculated as √(L/C). With L = 250 μH and C = 1000 pF, the calculation yields √(250x10−6 / 1000x10−12) = √250,000 = 500 ohms.
