The exciting current for a certain 50-kVA, 480-240V, 60 HZ transformer is 2.5 percent of rated current at a phase angle of 79.8 degrees. Sketch the equivalent circuit and phasor diagram for the no-load conditions and, assuming operation is in the step down mode, determine (a)the exciting current; (b)the core loss component of the exciting current; (c)the magnetizing current; (d)the core loss.
An LVDT (Linear Variable Differential Transformer) is used in an accelerometer to measure seismic-mass displacement. The LVDT and signal-conditioning output is 0.31 mV/mm with a +/- 2 cm maximum core displacement.
An otherwise-ideal op amp, known to have an open loop gain of 10^4 V/V , is measured in a circuit to have an output voltage of -3 V. While it would be difficult to measure, what would you expect the voltage from the negative terminal
A given device has been determined that it attenuates 4.8dB in power from its input terminal to its output terminal. What is the output power in watts if a 150-W input has been launched into a system that has two of this type of devices
A 10 uH inductor is connected to a circuit such that prior to t = 0 the current through the inductor is 10 mA. After t = 0 the current through the inductor is iL(t) = 10e^(-1000t) mA where t is time in seconds. a) Determine the expression for indu..
Defibrillator machines are used to deliver an electric shock to the human heart in order to resuscitate an otherwise non-beating heart. It is estimated that a current as low as 17 mA through the heart is required to resuscitate.
Given an object with a mass of 55 lbm, who starts at rest but experiences a constant horiz. force due to resultant force applied for 10 seconds. The work of the resultant force is 7,782 lbf*ft.
A certain mixer is producing the following frequencies: 900 kHz, 700 kHz, 500 kHz, and 200 kHz. What are the two most likely input frequencies?
A Silicon wafer has a uniform doping density of 8 xl018 atoms cm-3 of Arsenic and 2.5 x 1019 atoms cm-3 of Phosphorus. Assume that all Arsenic atoms are fully (100%) ionized at room temperature but the Phosphorus atoms are 80% ionized.
A batch process which involves filling a tank with liquid, mixing the liquid and draining the tank, is automated with a PLC. The specific sequence of events is as follows
