Consider the two-pole two-phase induction motor having two windings displaced 90° in space shown in Figure.The fields produced by the windings are given by Ba = Kia(t) cos(θ ) and Bb = Kib(t) cos( θ-90°). The two-phase source produces currents given by ia(t) = Im cos( t) and ib(t) = Im cos( ωt- 90° ). Show that the total field rotates. Determine the speed and direction of rotation. Also find the maximum flux density of the rotating field in terms of K and Im.
Electric field due to planar charge density. An infinite plane, charged with a uni form surface charge density ρo is immersed in a dielectric of permittivity e. Calculate the electric field intensity everywhere in space.
Positive charge Q is distributed evenly on y axis between y = 0 and y = a. A negative charge -Q is located at a distance x from the rod on the x-axis.
Develop a system to help students learn Morse Code. The system will have one input and 26 outputs (one per letter). The user sends in Morse Code pulses on the input, and as characters are completed the appropriate letter is lit up momentarily.
two identical CE amplifiers are connected in cascade. The first stage is fed with a source eVsig having a resistance Rsig= 10k ohms. A load resistance Rl=10K ohms and is connected to the collector of the 2nd stage.
An N-type silicon substrate with the doping density of 1x10 15 cm-3 Arsenic is to be converted into p-type by Boron diffusion, so that the resistivity at T=75C is 5 O-cm. All atoms are fully ionized.
An npn BJT operating with its base-emitter junction forward biased, its base-collector junction reversed biased, and negligiblehole-electron recombination in the base has an emitter current composed of 98% electron flow and 2% hole flow.
Using Multisim, design a mod-100 BCD counter that drives a 2-digit, 7-segment display. The count sequence will be 0 through 99. Blank leading zeros in the tens digit of the display.
Half of the area within the plates is filled with paper and the other half is filled with air.
A particular communications system has 2 identical receiver stages connected in cascade, each with gain 7 dB and noise figure 4 dB. Compute the noise figure of the combination assuming the stages are impedance matched.
A (3V, 300mA) flashlight bulb is to be used as the dial light in a 120V radio. What is the resistance of the resistor that should be connected in series with the flashlight bulb to limit the current
the -3 dB frequency for low pass Butterworth filter is 2.5 kHz. The stop band begins at 3.8 kHz, with an attention of 35 dB. Determine the minimum order of the filter if the sampling rate is 8 kHz
A hot-air balloon is rising upward with a constant speed of 3.86 m/s. When the balloon is 9.27 m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground
