A shunt dc motor has RA = 0.1 ? and VT = 440 V. For an output power of 16.1 hp, nm = 1,213 rpm and IA = 103 A. The field current remains constant. Find the the rotational power loss in hp.
Let x[k] be a time-domain sequence and X[r] be its DFT. (When written as vectors, unless stated otherwise, always assume the first entry in the vector is at k=0 or r=0, respectively.) If x[k] = [5, 9, 6, 10]
AC Analysis Gain at Midband (with bypass capacitor in circuit) Connect the bypass capacitor using the switch.
For random ergodic voltage signal, I make a histogram of sample voltages and note that they form a Gaussian distribution. estimate the following moments over a number of samples taken at diffrent time points alont the voltage signal
A 60 hp, 3-phase motor absorbs 50 kW from a 600 V, 3-phase line. If the line current is 60 A, calculate the following: (a) The efficiency of the motor (b) The apparent power absorbed by the motor (c) The reactive power absorbed by the motor
RC series circuit c=10,r=1,vs=15 and intial capictor charge q(0)=0.01. write standard form of the diffierential equations which describe the capictors charge q(t) t>0, obtain integration factor u(t),and determine general solution for q(t)
Dissipations of Power in Lightbulbs, An incandescent lightbulb rated at 100 W will dissipate 100 W as heat and light when connected across a 110-V ideal voltage source
Determine if the following CT signal is periodic. calculate the fundamental period T0 for the CT signal: x(t) = 2cos(4*pi*t/5)*sin^2(16t/3)
Design a CMOS Differential pair amplifier with a low frequency gain of at least 30dB, while driving a resistive load 50 ohm. The available circuit components are NMOS transistor, PMOS transistor, resistors, capacitors and inductors.
A three-phase, 60Hz, wye-connected synchronous generator has balanced line-to-line voltages of 480V at its terminals. The generator is supplying power to two balanced and delta connected, three-phase loads. the first load is made up
An incident -ray photon is scattered from a free electron that is initially at rest. The photon is scattered straight back at an angle of 180 degrees from its initial direction. The wavelength of the scattered photon is 9.00×10^-2 nm.
MOS (p and n) npn and pnp transistors with parameters given in the text or select your own by using industrial data sheets, available on the internet. Also resistors, capacitors, and power supplies (10 V, 5 V, and 3.3 V) are available.
