A certain amplifier has an open circuit voltage gain of unity,and input resistance of 1 MΩ, and an output resistance of100Ω. The signal source has an internal voltage of 5 Vrms and an internal resistance of 100kΩ. The load resistance is 50Ω. If the signal source is connected tothe amplifier input terminals and the load is connected to theoutput terminals, find the voltage across the load and the powerdelivered to the load. Next ,consider connecting the load directly across the signal source without the amplifier, and againfind the load voltage and power. Compare the results. What do you conclude about the usefulness of a unity-gain amplifier in delivering signal power to a load?
The LM358 op amp can be a single or dual supply op-amp. This mean that it can operate with just a single supply i.e. + 5 volt or with dual supplies i.e. (+ and -) 5 volt supplies. With a inverting configuration with dual supplies (+5v and -5v) bei..
The s-plane diagram of a filter shows that it has a cluster of four poles in the left-half s-plane that are arranged in a semi-circle near +/- j628. The filter also has two zeroes at the origin.
Construct a 2 rung ladder schematice with an AC source with overload protection in the main line, the schematic will contain 1 rung with a lamp load controlled by a N.O. Push button. On the second rung there will be a N.C.
Four point charges of 1 C are located at the corners of a square with a side a =1 m. Find the magnitude of the force experienced by each charge.

An equilateral glass prism w/ an index 1.42 has a beam of light incident on one face at an angle of θi to the normal. Determine the angle at which it emerges from an adjacent face of the prism.
a filamentary conductor carrying current I in the z direction extends along the entire z axis. At z=0 it connects to a copper sheet that fills the x>0 and y>0 quadrant of the xy-plane. Set up Biot-Savart law and find H everywhere on z axis.
A 5-MVA, 66:13.2kV, three-phase transformer supplies a three-phase resistive load of 4,500kW at 13.2kV. What is the load resistance in ohms as measured from the line-to-neutral on the high-voltage side of the transformer, if it is connected in Y
A certain unity feedback control system has the closed-loop transfer function: T(s)= Y(s)/R(s)= (s/10+1)/((s/100+1)*(((s/20)^2)+s/20+1))) a) What is the estimated rise time b) What is the estimated overshoot
The program will store these values into an array and call a function that will return the average of the temperatures. It will also call a function that will return the highest temperature and a function that will return the lowest temperature.
A six pole, 400 V d.c. motor draws 110 A from the supply. The shunt field resistance is 200 Ohm and the armature resistance is 0.5 Ohm. The armature is wave wound with 600 conductors operates at a speed of 1200 rev/min when supplying full load.
