A phasor current of (1 phase angle 0 degrees)A is flowing through the series combination of 1 ohm, 1H, and 1F. At what frequency is the amplitude of the voltage across the network twice the amplitude of the voltage across the resistor?
Devise a circuit that could be used with a conveyor belt which is used to move an item to a work station. The presence of the item at the work station is detected by means of breaking a contact activated by a beam of light to a photo sensor.
Design a 3rd order Butterworth High-Pass filter with a Fc of 2kHz and a passband gain of 2. Find the gain and critical frequencies of each individual stage. Plot the gain portion of the bode plot.
A temperature of 200 oC is measured using a thermopile having three pairs of measuring junctions as shown in the figure below. The reference junction temperatures are set at room temperature of 25 oC.
The address field of the instruction (stored at W + 1) is designated by the symbol Y. The operand used during the execution of the instruction is stored at the effective address symbolized by Z. An index register contains the value X.
A digital device has a decimalindicator showing up to three significant figures. An equivalentanalog device has 1000 divisions over the span. Can we determine which instrument is more accurate Explain.
A 500-kVA, 60Hz, 5000V, Y-connected, 10 pole synchronous has internal parameters of Armature Resistance 1ohm amd Synchronous Reactance 10ohms. The generator is operating at rated values and 0.9 pf leading.
In cylindrical coordinates ,let D = (pa + za )/[4pie(p^2+z^2)^1.5].Determine the total flux leaving: p z a) The infinitely long cylindrical surface p=7; b) the finite cylindrical,p=7,l z l less than equal to 10.
Design a circuit that satisfies the equation VOUT = - 3 * VB - 2 * VA. Draw the circuit schematic identifying supply voltages and show your work on component selection
A delta-connected source has a line-to-line voltage rating of 470 Vrms. Its wye-connected load has a power rating of 2125 W with a pf of .85 lagging. Find the rated phase currents.
Assuming that there is no frequency-dependent component of the load (i.e., D = 0), find the steady-state frequency deviation and the corresponding new generation of each unit. Use 1000 MVA as the p. u. (per-unit) base.
Design a hardware implementation of a binary tree which functions as follows Each node of the binary tree has a unique address ( as discussed inclass). Given the address (A) of a node, and a datum (I), the machine willwrite I in node A.
Let E = y ax V/m at a certain instant of time, and calculate the work needed to move a 3 C charge from (1,3,5) to (2,0,3) along the straight line segment joining: a.) (1,3,5) to (2,3,5) to (2,0,5) to (2,0,3)
