Find I1 and I2 in the circuit of Fig. 13.84. Calculate the power absorbed by the 4-Ω resistor.
A box contains resistors whose values are independent and areuniformly distributed between 100 and 120 ohms. If two resistorsare selected at random and connected in series, find a. the most probable value of resistance for the series combination
calculate the short-circuit current of a three-phase delta-wye connected transformer if the short circuit occurs between phase A and the neutral at the low voltage side, and the transformer is supplied by a 13 kV line-to-line voltage.
The read arm of a computer disk drive has the transfer function of G(s) = 1000/s^2. Design a digital controller that has a bandwidth of 100 Hz and a phase margin of 50 degrees. Use a sample rate of 6kHz.
(a) Determine free electron and hole concentration.(b) Calculate the effective density of states at valence band, Nv. Given that ni = 1x1010 cm3 and kT = 0.026.
The characteristic length / is the length of travel of the fluid in the boundary layer across the shape surface. Compare this correlation to that given for a sphere to test its utility.
The speed of a 20-hp, 300-V, 1800-rpm separately excited DC motor iscontrolled by a three-phase full converter drive. The field currentis also controlled by a three-phase full converter and is set tomaximum possible value.
Determine the decimal value of each of the following SIGNED binary number displayed in the 2's complement form: a. 10011001 b. 01110100 c. 10111111
Identify and describe three different ways to manufacture resistors. These variations can be "form factor" or the technique used to establish the resistance. Provide an example of a resistor de-rating curve from a manufacturer
Write a 68000 assembly language subroutine, ROTMEM, which rotates the elements (words-size) of an array stored at location point to by (A0). The depth of the array is stored as the first element.
A 10 MVA, 6.9 KV. star connected generator has positive, negative and zero sequence reactance of 25, 20 and 7% respectively. An inductive reactor with 6% reactance based on the rating of the generator is placed in the line from neutral to ground.
What is Corona effect on transmission Line?And states some sources of Corona loss.
Hecreates a frequency spectrum and plots it. He observes a peak inthe spectrum at 105 Hz. With just one sampling rate, however, Jared cannot be sure that this is the true or actual frequency componentin his signal - perhaps there is aliasing.
