Assume that one of the pumps uses a1/4hp DC shunt motor with an input voltage of 115VDC that pulls 1.6A running at 1500 rpm. The filed resistance for the motor is 600 ohms and the armature resistance is 8.5 ohms. Find the constant KT for the motor..
A 60-Hz, single phase source with V= 277 at angle 30 degree volts is applied to a circuit element. Determine the instanaeous power, real power, and reactive power absorbed by determine the source power factor and state lagging or leading.
The balanced 60Hz waveform sample that we must modulate is the point where t=4.4ms. The DC voltage from rail to rail is 300V. assume the q axis and a axis are in same direction. The use of mathCAD is recommended.
An airplane has a mass of 3*10^4 kg and takes off under the influence of a constant net force of 35 000 N. What is the net force that acts on the plane's 80-kg pilot, assuming that he has the same acceleration as the plane
The charge entering the positive terminal of an element is q(t) =-30e-4t mC. If the voltage across the element is120e-2t V, determine the energy delivered to the elementin the time interval 0
A 160-ft-diameter parabolic antenna is driven by a 10-W transmitter at 4.3 GHz. Calculate its effective radiated power (ERP) and its beamwidth.
1. What should the length of an antenna be if it is going tobe used to send data at 145.01MHz, assume a 1/4λmonopole antenna is used. 2. The impedance of an antenna was measured as z = 17 -j470Ω what does this mean
The open-loop gain of a compensated op-amp is measured as follows:5.1´103 at100 kHz and 8.3´103 at10 kHz. Calculate its 3dB frequency, its unity-gain frequency, and its dc gain.
Water is flowing out of a tube at a near constant volumetric flowrate, V .If a graduated cylinder is used to collect a certain volume, v , of the water, and a timer is used to measure the time, t, required to collect the volume of water, the volum..
