A 50 ohmlossless air transmission line is terminated in a load impedance ZL = 12.5 + j20 ohm. Find the following using a Smith Chart:
i) the load admittance YL.
ii) the closest distance to the load plane where the normalized admittance on the line is 1 + jbN.
iii) the length of a short-circuited stub of characteristic impedance Zos=100 ohm which, upon placement in shunt with the line at the 1 + jbN admittance point, produces impedance matching on the line so that there exists no reflected wave to the left of the short-circuit placement plane.
Assume that an additional inductance can be inserted in series with the load. Also assume that the converter has no freewheeling diodes. Calculate the added inductance that leads to a conduction period of 180 degrees when alpha = 30 degrees.
calculate ratio of the area to volume for unit cube, a unit sphere inscribed inside the cube and as right cylinder inscribed inside the cube.

A semiconductor company has the following costs associated with Product X: - Fixed cost of $1B ($1,000,000,000) - Die cost of $6 at a die yield of 50% - Testing and packaging cost of $3 per die - A final test yield of 90% with a product volume of 500..
Attenuation of received power with change in transmission frequency and distance between the antennas
Given the following function in product-of-sums form, not necessarily minimized, F(W,X,Y,Z) = (W + X' + Y')(W' + Z')(W + Y), Re-express the function in the canonical sum-of-products form. Use little m notation.
A ideal transformer is rated at 4800/480 volt, at 75KVA. it is connected as a step down auto transformer. find the line and load voltages, turns ratio and total apparent, real and reactive power at full load and at 60% rated load at a power factor..
Show that the power in a three-phase, three-wire system with balanced loads is constant at every instant. Deduce an expression for the power in terms of the line voltage, line current, and the power-factor.
