A 110 V d.c. generator supplies a lighting load of forty 100 W bulbs, a heating load of 10 kW and other loads which consume a current of 15 A. Calculate the power output of the generator under these conditions.
Find the dimension of the window, as measured at the top of the oxide, after ideal isotropic etching (i.e. no overetch). Draw a cross section of the window opening with the resist still on.
Calculate the pu circuit parameters of the transformer. Determine its efficiency and voltage regulation at full load 0.8 pf lagging. Calculate also the maximum efficiency and the load (0.8 pf ) at which it will occur.
Determine the voltmeter reading one time constant after the switch is closed. - Find the current iC two time constants after the switch is closed.
The factorial n! of a positive number (integer) is defined by n! = n.(n-1).(n-2)...3.2.1, where 0! = 1. Write a user-defined function that calculates the factorial n! of a number. For function name and arguments use y=fact(x)
perform Cause-Effect Analysis on the Equipment Check-Out System (ECS) and document your findings using the Problems, Opportunities, Objectives, and Constraints Matrix.
A chopper controlled electric train is powered from a 1500 VDE supply. The power semi- conductor switch element hasaminimum effectice ON time of 40 Ms. during starting and slowspeed running, the output of the chopper has to go as low as 15 V.
If the power factor of the motor be changed to 0.866 lagging. Determine the reading of the two wattmeters, the total power remaining unchanged.
Determine the pressure gradient at the stagnation point of Problem.- For the velocity potentials given below, find the stream function and sketch the streamlines.
Determine the minimum bandwidth, baud, and bandwidth efficiency for the following bit rates and modulation schemes - 8-QAM and 16-QAM. Fb = 2400 bps Fb = 4800 bps Fb = 9600 bps
The signal x(t)=10cos(t)+10sin(10t) is input into the following systems: a) \(H(s)=100/(s^{2}+10s+100)\) b) \(H(s)=s^{2}/(s^{2}+10s+100)\) calculate the output for each system.
An input signal x(t) = cosωct is sampled by an ideal sampling function with ωs= 1.5 ωc. The sampled signal is then filtered with an ideal low pass filter H(ω)= rect(ω/1,5ωc) to form an output signal y(t) a. Sketch the fourier transform of the sampl..
