Magnetized plasma with an ADE method. The method used in this chapter for ferrites is a type of auxiliary differential equation method. It turns out that one can also write an ADE-type method for the magnetized plasma. Derive such a method, using the frequency-domain version of Equation (11.29) and following the logic in the ferrite section.
A room is heated by an iron that is left plugged in. Is this a heat or work interaction? Take the entire room, including the iron, as the system.
A circuit designer requires a gain of 25 (+or -) 1% V/V using an amplifier whose gain varies by a factor of 10 over temperature and time. What is the lowest gain required. The nominal gain. The value of B(beta).
A three-phase steam-turbine synchronous generator is connected to an infinite bus. The generator excitation current is IF=1000 A at the time of synchronization with the bus. The generator has a synchronous reactance of Xs =1.5 per unit.
Derive the ripple factor of ?-filter with neat sketch. (or) Discuss a FWR with ?-filter.
An infinite plane in the xz plane carries a uniform surface charge density s1 = 75 nC/m2. A second infinite plane carrying a uniform charge density s2 = 30 nC/m2 intersects the xz plane at the z axis and makes an angle of 30°
What is the maximum closed-loop gain available from a single amplifier? From 2 identical amplifiers used in cascade? (See the result for 2 amplifiers in cascade developed in Problem 2.73 on page 119 of the Text).
Design a circuit to give uninterrupted 5 V dc power supply with 110 V 60 Hz line voltage as input. The dc output should be available in case of power outage (110 V line supply). In case of line failure, the circuit should switch to backup source t..
For 16-QAM modulator, change the reference oscillator to cosωct and determine the output expressions for the following I, I', Q, Q' with input conditions: 0000, 1111, 1010, 0101.
A. Fourier Transform properties (a) If x ( t ) is real and even, show that its Fourier transform is real for all ω (i.e., its imaginary part is identically 0). (b) If x ( t ) is real and odd, show that its Fourier transform is imaginary for all ω (..
Write the formula for the magnetization volume current density J M and magnetization surface current density JMS in terms of magnetization vector M. 4. A sphere has permanent magnetization where is a positive constant.
A star-bus hybrid topology consists of a main three branch star toplogy with each branch connecting three stations in a bus topology. This toplogy is changed to a new bus-ring hybrid topology with main five station bus topology.
The current flowing through a 300-mH inductance is given by 5e(-200t). Find expressions for the voltage, power, and stored energy. Sketch the waveforms to scale for 0
