3. A 6 m section of 150 ? lossless line is driven by a source with $v_g(t) = 5cos(8 \times 10^7 t - 30^\circ)$ (V) and $Z_g = 150 \Omega$. If the line, which has a relative permittivity $\epsilon_r = 2.25$, is terminated in a load $Z_L = (150 - j50) \Omega$, determine: (a) $\gamma$ on the line. (b) The reflection coefficient at the load. (c) The input impedance. (d) The input voltage $V_i$. (e) The time-domain input voltage $v_i(t)$.

Step 1
The characteristic impedance of a transmission line is given by the formula Zc = sqrt(L/C), where L is the inductance per unit length and C is the capacitance per unit length. Since the line is lossless, there is no resistance per unit length. Show more…

An $a b c$-phase-sequence balanced three-phase source feeds a balanced load. The system is connected wye-wye and $/ \mathbf{V}_{a n}=0^{\circ}.$ The line impedance is $0.5+j 0.2 \Omega,$ the load impedance is $16+j 10 \Omega$, and the total power absorbed by the load is $2000 \mathrm{W}$. Determine the magnitude of the source voltage $\mathbf{V}_{a n}.$
A lossless transmission line with Z0 = 50 Ω is 30 m long and operates at 2 MHz. The line is terminated with a load ZL = (60 + j 40) Ω. If the velocity of wave on the line is 0.6*C. Find: (i) Reflection coefficient (ii) Standing wave ratio (iii) Input impedance. Solve using analytical approach. (without smith chart) Assume suitable data if necessary.

In a balanced three-phase wye-wye system, the source is an $a b c$ -sequence set of voltages and $\mathbf{V}_{a n}=120 / 50^{\circ} \mathrm{V} \mathrm{rms}$ The load voltage on the $a$ phase is $110 / 50^{\circ} \mathrm{V} \mathrm{rms}$, and the load impedance is $16+j 20 \Omega$. Find the line impedance.
