For the oscilloscope display of given figure:
a. Determine the period of each waveform.
b. Determine the frequency of each waveform.
c. Find the rms value of each waveform.
d. Determine the phase shift between the two waveforms and which leads or lags.
A 600V, 150hp, DC series motor operates at it's full-ratedload at 600 RPM. The armature resistance is 0.12 ohms and the series field resistance is 0.04 ohms. The motor draws 200A at full load.
A 2 farad capacitor is charged up to 400v by a dc power supply. How long in seconds would it take to discharge the capacitor to a safe stored energy level of 1 joule using a 1k ohm high wattage resistor bank.
Assume that the load is star connected with the neutral disconnected. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Plot the neutral voltage Plot the phase to neutral voltage for phase a.
The transfer function of a system is given below. Find its impulse response in n-domain. Hint: First expand using partial fraction expansion and then perform its inversion using z-transform tables H(z) = 1/(z-0.5)(z0.5)

design a simple 4-bit binary divider , takes two numbers from only 0 to 9. This circuit will perform A/B and B > A will give zero, the answer will be just the integer part ( for example : o111 / 0010 = 0011 ).
Create 2 equations with 2 unknown variables. For example, one equation would be ax + by = c and the other equation would be dx + ey = f where x and y are the variables and a, b, d, and e are coefficients for the variables and c and f are numbers.
figure out how to plot the response of a system given an input. transfer function for the system is: H(s) = 1000/(s^2 + 110s + 1000) input is periodic, and represented by: u(t) - u(t-pi/2)
Determine the time required for the current iR to drop to 1 mA. - Find the voltage vL at t = 1 ms. - Calculate vR3 at t = 5τ.
A) the required step-up voltage ratio for satisfactory performance. B) the voltage ratio of a standard buck-boost transformer that most closely meets the requirements of the load. C) the voltage at the load with the buck-boost transformer installed.
1) A 5H inductor changes its current by 6 A in 0.4s. The voltage produced at the terminals of the inductor is 2) An RL circuit has R=2 ohms and L=4. The time needed for theinductor current to reach 40% of its steady state value is
The figure shown below shows a one-line diagram of a simple power system containing a single 480 V generator and three loads. Assume that the transmission lines in this power system are lossless, and answer the following questions. Assume that..
