Simplest equivalent circuit topology using lumped elements:
For each of the Smith chart traces below, sketch (at the right of each chart) the simplest equivalent circuit topology using lumped elements. Note that the first chart's trace does not lie exactly on the unit circle:
The chart traces on the right side both begin at f=1.0 GHz and lie approximately on the r=0.5 circle, starting at the x=-2.0 circle. With this information, find the values (to two significant digits) of the two components that at 1 GHz dominate the equivalent circuits you've drawn.
Induction motors are often braked rapidly by a technique known as plugging, which is the reversal of the phase sequence of the voltage supplying the motor. Assume that a motor with
In order to demonstrate aliasing, make a plot of the signal x(t) = 3 cos 2π10t - cos 2π30t which approximates a square wave with W = 30 Hz. If the sample points are taken at
In a 3-stage continuous ultrafiltration process, a solution is concentrated from 5 gm/Liter to 50 gm/Liter of protein. The final retentate is to have a flow rate of 1000 L/hr. The
Q. In an amplifier, the maximum voltage gain is 1500 and occurs at 1kHz. It falls to 1060.5 at 20kHz and at 20Hz. Determine (i) lower cut-off frequency (ii) upper cut-o
A 3-phase, wye-connected, 11.8 kV, 100 MVA turbo- generator of 0.8 power factor lagging has a synchronous reactance of 2.0 p.u. on rating. The generator is driven by a steam turbin
Q. Explain the drain characteristics of JFET with external bias? It gives relation between Id and Vds for different values of Vgs.(which is called the running variable). The ab
Q. A three-phase, three-wire 208-V system is connected to a balanced three-phase load. The line currents ¯ IA, ¯ IB, and ¯ IC are given to be in phase with the line-to-line voltage
Rectifiers As discussed above the purpose of the rectifier is to convert the incoming ac from a transformer or other ac source to some form of pulsating dc. That it i
Registers Various registers shown in figure are discussed below in detail.
Calculation of Aggregate Technical and Commercial Loss The concept of AT&C loss was introduced within 2001-02. The AT&C losses are presently in the range of 18% to 62% in seve
