The power bus arrangement shown in Fig.P4.15 is used to transmit 5 V dc to a 10-A load. The bus bar is 5 m long.
a. What is the dc voltage drop in the distribution system?
b. What is the characteristic impedance of the power bus?
c. If the load current suddenly increases by 0.5-A, what is the magnitude of the transient voltage on the power bus?
Three single phase transformers are used to form a three-phase transformer bank rated 13.8kV (delta)/120kV (wye). One side of the transformer bank is connected to a 120kV transmission line.
construct a vertical line on your I versus V graph at the point V=5V. this line will intersect each of the sloping lines at two separate points. explain the significance of these intersections.
A half-wave dipole antenna has an input impedance Zant = 73.2 + j42.5 ohms. Design an open-ended shunt stub matching network to match this antenna to a 50ohm line.
A 24-volt automotive battery is connected to two headlights, such that the two loads are in parallel; each of the head lights isintended to be a 75-W load, however, a 100-W headlight is mistakenly installed.
An asset with a first cost of $50,000 is depreciated by the MACRS method over a 10-year period. If the asset will have a $20,000 salvage value, its book value at the end of year two will be closest to
Calculate the distance, D at which communication from the space craft will be lost again? Assume both antennas are ideal.
In fission reactors one deals with neutrons having kinetic energies as high as 10 MeV. How much error is incurred in computing the speed of 10-MeV neu trons by using the classical expression rather than the relativistic expression for kin..
Create a Verilog module that implements 4 bit full adder-subtractor with overflow detection. You may use Verilog bitwise operators and gate primitives, but no mathematical operators or behavioral Verilog syntax.
An emitter follower, when driven from a 10 kohm source, was found to have an output resistance Rout of 200 ohm. The output resistance increased to 300 ohm when the source resistance was increased to 20 kohm.
Calculate the sag in a 90-yard span of a 0.035 -in^2 overhead line when covered with ice to a radial thickness of 5/8 in, in a wind that exerts a pressure of 9 lb/ft^2, assume the breaking load as 1620 lb and the weight of the conductor as 0.1 lb/..
Machine A was purchased three years ago for $10,000 and had an estimated market value of $1,700 at the end of its 10-year life. Annual operating costs are $1,350. The machine will perform satisfactorily for the next seven years.
A common-source FET amplifier has an RD = 1.0 k ohms. How much does the gain change when a load resistance of 1.0 k ohms is capacitively coupled to the drain
