An inductor having aseries resistance of 60Ω and an inductive reactance of60Ω is connected to a 120V, 60Hz, AC suplply.a) Determine thecurrent through each element and the total power taken by thes eries combination and the power factor of thecombination.b) Using thesupply-voltage phasor as the reference, sketch a phasor diagram forthe circuit.
The equivalent inductance of the primary and the secondary circuits is .02H. The frequency of the primary windings is 10Hz. Assume that the drag force is 500N and the friction force is 2kN. Compute the voltage across the primary windings when the ..
Independent of circuit details, for a digital input code of (b1, b2, b3, .... bn), the output of an n-bit digital to analog conversion output is of the form output = K (b1 + (b2/2)+ (b3/4)...+(bn/ 2^n-1)) For a particular 5 bit DAC the output volta..
Determine the 8-bit sign-and-magnitude, 1's complement, and 2's complement representations for each of the following decimal numbers: +36, -84. (Note: Be sure to represent +36 as a positive number and -84 as a negative number.)
Maximum value of frequency deviation is fixed at 75 kHz for commercial broadcasting by radio. Modulation frequency W = 15 kHz, then find the transmission bandwidth of signal and deviation ratio.
Oil (density 0.91 g/cm^3) flows in a pipe (see fig.) and the flow rate is measured via a mercury manometer (density of Hg=13.546 g/cm^3). If the difference in height between the two legs of the manometer is 0.78 in.
Question about Complex power, If an electrical load operates at 240 Vrms.The load absorbs an average power of 8kW with .8 lagging power factor
If each gold atom donates one electron to the gold matrix at room temperature, estimate the electron concentration of gold. Is gold a conductor?
Give a narritve for a cruise control system of a car. Include all relevant inputs and outputs. Design a flowchart and ladder diagram. Every element on the ladder diagram must be labelled and described.
Two generators are connected in parallel to the same bus bar and each has an inductive reactance of 10% on rating. Generator 1 is rated 2,500 kVA and 2.4 kV, and generator 2 is rated 5,000 kVA and 2.4 kV.
A long hallway has three doors, one at each end and one in themiddle. A switch is located at each door to operate the lights along the hallway. Label the switches X, Y, and Z. Design a logicnetwork to control the lights.
Calculate the torsional spring stiffness constant for a steel shaft 0.5" in diameter and 2.5 ft long.
An LTI system has an impulse response h(t) = e^(t) u(-t),where u(t) is the unit step signal. (a) Give a differential equation description for the system. (b)Suppose that an input signal is given as x(t) = e^(-t) u(t). Determine the output response.
