Suppose you are given an op amp and 20 resistors, each with resistance R. Assuming ideal op-amp behavior, design a circuit which, given input voltages v1, v2, v3, and v4, will deliver a voltage vo, given by vo = 2v1 + 4v2 -2v3-4v4 to a load resistor RL. Your answer should include a drawing of the circuit diagram for your op-amp circuit, including the load resistor and all input voltages, and an analysis showing that the circuit performs the desired function. Note that you may not need to use all the resistors provided.
A capacitor in an RC circuit with R = 5.00 W and C = 6.00 mF is being charged. What is the time required for the capacitor voltage to reach 86.5 percent of its steady-state value
Derive an expression for the surface current density (Js) on the conductor surface. In a diagram show the vector relationships among Js , the magnetic field Hs at the surface of the conductor, and the incident electric field vector.
Apply the classical Runge-Kutta method to solve the following initial value problem given y(0)=1 and the step size h=0.1. Verify solution using MATLAB. Plot the solutions obtained by using ode45 and dsolve. Compare the graphs and provide an explan..
The SV curve can be used to understand the impact of constant power factor shunt compensation support. In this case, the receiving end is injected with a specific amount of reactive power so that the receiving end maintains a constant load power f..
A four-pole armature is to generate an average e.m.f. of 2.0V per conducter, the flux per pole being 25mWb. Calculate the speed, in r/min, at which the armature must rotate.
The time has come for XelPharm to expand. The board of directors has purchased another warehouse for a second distribution facility. It's located in an industrial area, about eight miles from the company's headquarters.
If we use the PC-relative addressing mode, and want to allow control transfer between instructions up to 50 locations away, how many bits of a branch instruction are needed to specify the PC-relative offset
Then, solve each Problem using hand calculations. A three-phase, 765-kV, 60-Hz transposed line is composed of four ACSR 1,431,000, 45/7 Bobolink conductors per phase with flat horizontal spacing of 14 m. The conductors have a diameter of 3.625 cm ..
A load is drawing 10 A rms when connected to a 1200 V rms supply running at 50 Hz. If the source is operating at a lagging PF of 0.9, calculate (a) the peak voltage magnitude; (b) the instantaneous power absorbed by the load at t = 1 ms
Give three advantages of a three-phase system over a single-phase system There are two basic three-phase connections, the wye connection and the delta connection. Draw a labelled diagram showing the wye connection
A.) We would like to use a series lumped element b to match this load. What is the length of the line where the normalized input impedance is z= 1-jb(d/\lambda). If the rfequency is 1GHz , find the value of the lumped element(C or L).
The rate of production of ATP in the cell is about 10 million molecules per second. The steady-state number of ATP molecules in the human body is about 0.1 mol. The number of cells of a human body is approximately 1014.
