1. When the current in a coil changes from 2 A to 12 A in a time of 150 ms, the emf induced into an adjacent coil is 8 V. Calculate the mutual inductance between the two coils.
2. The mutual inductance between two coils is 0.15 H. Determine the emf induced in one coil when the current in the other decreases uniformly from 5 A to 3 A, in a time of 10 ms.
Sketch the recovered analog signal spectrum if an ideal low pass filter with a cutoff frequency of 4 kHz is used to filter the sampled signal in order to recover the original signal.
Two tire-quality experts examine stacks of tires and assign a quality rating to each tire on a 3- point scale. Let X denote the rating given by expert A and Y denote the rating given by B. The following table gives the joint distribution for X and..
For the static rotor resistance control considered in the text for an induction motor drive, develop the fundamental frequency equivalent circuit of Figure 16.1.23.
Develop a open-loop model of the traction drive shown in Figure and please derive its transfer function - Design a switch mode PWM DC-DC converter for the speed regulation of the DC motor.
The transmission line has an impedance of 600 ohms and is terminated in a load of 600 ohms. The transmitter delivers an average power of 0.1 W to the input of the line.
Calculate the value of vL developed across a 300 H coil when the instantaneous rate of change in component current equals 500 mA/s.
Consider a cylindrical cavity of diameter D=100 mm and depth L=50 mm whose sidewall and bottom are diffuse and gray with an emissivity of .6 and are at a uniform temperature of 1500 K. The top of the cavity is open and exposed to surrounding that ..
Rework Example 9.11 with everything the same except assume SIRdB; min= 10 dB.
A balanced Wye connected load of 15 + j9 Ω/phase is being fed by a Wye connected source. Each of the three lines feeding the load from the source has 0.5 + j0.3 Ω impedance. The voltage at the load is 440 VLL .
The light from a cameras electronic flash is produced when a high voltage obtained by charging a capacitor is applied to electrodesin a xenon-filled flash bulb. (a) to what voltage would a 60-microfarad capacitor be charged by a6mA current lasting ..
Goal of project is to model a system and to design a controller for the system so that the closed-loop system performs satisfactorily - Design a switch mode PWM DC-DC converter for the speed regulation of the DC motor.
