Question

The characteristic impedance of a loss less transmission line is given by.

Options

• Z₀ = `sqrt(LC)`

• Z₀ = `sqrt(L/C)`

• Z₀ = `sqrt(C/L)`

• Z₀ = LC

Answer 1

Z₀ = `sqrt(L/C)`

Explanation:

Because the lossless line R = O = G, the attenuation constant a = 0 and the characteristic impedance Z₀ are both real Z₀ = `sqrt(L/C)`.
