From given Example, sketch the scaling factor for the output transistor width as α varies from near zero to π/2.
Example:-Determine the amplitude of the first harmonic of the transistor drain current in Figure for a conduction angle of θ.
A single phase transformer has the following rating: 120 kVA, 2000 V/100 V, 60 Hz with 1000 primary turns. Determine: (a) the secondary turns (b) the rated primary and secondary currents (c) the maximum flux
Convert the current source and 6.8-Ω resistor to a voltage source. - Find the magnitude and direction of the current I1.
Calculate the electric field strength E1 (Newton/Coulomb) at the surface of an ellipsoid with major/minor axes of 0.3m x 0.4m x 0.4m, enclosing a charge q2 at the origin with 26.5 Coulomb. The medium is air.
Define Root Locus and Routh-Hurwitrz, Use Routh-Hurwitz to find vales of K so that L = k (s+1) / (s^2 +4) (s+10) has poles to the left of s= -2
This will allow us to represent 256 numbers in that range, and there are only 6 integers in that range, so we'll be able to represent 250non-integral values, such as, perhaps, 2.5. Assume we will use a representation with 0xff representing 5 and 0..
If the earth is considered to be a metal sphere(radius˜6371[km]), how much charge Q must bedeposited on its surface in order for an arc to be established inthe air. If the earth's surface was charged to the value byremoving all the electrons from ..
a sinusoidal voltage has a peak value of 15V, a frequency of 500Hz, and crosses zero with a positive slope at t=0.1 ms. write an expression for the voltage using a cosine function in terms of t and constant pi.
A current filament carrying current of 15 A in z direction lies along the entire z-axis.Find H in cartesian coordinates at point (√20,0,4)and(2,-4,-4)
Write the mathematical expression for the current iL and the voltage vL after the switch is opened. - Sketch the waveform of iL and vL from initial value to the steady-state level.
Consider the mapping of the unit circle (i.e., z = 1ejω, -π ≤ ω
Figure 5-47 shows part of a bicycle lighting system. The diodes are Schottky diodes. Use the second approximation to calculate the voltage across the filter capacitor.
For the op-amp in the voltage follower circuit in Figure P14.14, the open loop parameters are AO L = 5 × 103, Ri = 10 k, and Ro = 1 k.
