The phenomenon of dancing conductors can be more likely seen on what temperature regions?
A balanced Y-connected load of (300 + j100) Ω is supplied by a three-phase line 40 km long with an impedance of (0.6 + j0.7) Ω per km (line-to-neutral). Find...
In circuit simulation, we often create first the schematic design of the circuit and then convert it to its Netlist equivalent. Now for a change create the schematics equivalent of...
For the given long transmission line, find the theoretical steady-state stability limit for the 400-km line. Assume a 300Ω surge impedance, 6000km wavelength, and . Neglecting line losses. Note: Use...
A bolted short circuit occurs in the series R-L circuit of the given figure with V = 30 kV, X = 10Ω , R = 0.9Ω, and with maximum dc...
A sine wave having a frequency of 75 MHz is launched on a transmission line. (a) How long does it take from the time that the instantaneous voltage is zero...
A 105 MHz, 90 V peak signal is incident on a 50 Ω transmission line. The velocity factor k of this line is 0.85. The line is 125 meters long...
Referring to the figure shown above: (a) Determine the required length of a quarter-wave matching section which will eliminate standing waves and thereby provide a matched condition for a...
A certain microstrip line has fused quartz (ϵr = 3.8) as a substrate. If the ratio of line width to substrate thickness is w/h = 4.5, determinea) The effective relative...
A 50-Ω lossless transmission line is to be matched to a resistive load impedance with ZL = 100 Ω via a quarter-wave section as shown in the figure, thereby...
