The design specifications for a simple inverting amplifier require an input resistance of 10kOhm and a voltage gain, A=-6.2a) prepare a design using an ideal OpAmpb)If a real OpAmp with the properties: Ri=2MOhm, A=200k, Ro=75Ohm is used, what error in the gain and input resistance will result due to the non-ideal properties of the OpAmp
Suppose that the cost of electrical energy is $0.12 per kilowatt hour and that your electric bill for 30 days is $60 (power usage only, not including other charges or taxes) Assume that the power delivered is constant over the entire 30 days.
A. Two machinery options are described below. Calcuate the present value of each of the items specified. Assume an interest rate of 6% and a useful life of 8 years. Show all the necesary work to calcualte value.
what are two fundamental advances in the circuit theory that were developed in the 19th century in response to the challenges of telegraphy?
Knowledge about Circuit Analysis, A 5.1K resistor is connected between the cathode of a 6.2V zener diode and a 12V power supply
the magnetic circuit shown with a mean core length of 52 cm and a cross sectional area of 18 cm^2. the length of the air gap is 0.14 cm. Determine the battery voltage required to obtain a flux density of 1.2 T in the air gap. Use the magnetization..
A uniform plane wave propagates from one dielectric into another at normal incidence. Find the ratio of the dielectric constants such that the magnitudes of the reflection and transmission coefficients are both equal to 0.5.
A half-wave rectifier circuit with a 1-k ohm load operates from a 120-V (rms) 60-Hz household supply through a 10-to-1 step-down transformer. It uses a silicon diode that can be modeled to have a 0.7-V drop for any current.
A 480-V, 60Hz, 500-hp 0.85-PF-leading eight-pole delta-connected synchronous motor has a synchronous reactance of 0.6 ohms and neglible armature resistance. Ignore its friction, windage and core losses for the purposes of this problem.
a)Describe the difference between a relay logic system and a PLC control system. Are there any advantages of PLC control system over relay system. Explain the advantages in details with one example.
A 1,000 kVA, 3,200V, single phase 60Hz, 24 pole alternator/generator has an stator winding re-sistance of 0.1 ohm from line-to-neutral. The rotor is not a permanent magnet but a separately pow-ered electromagnet (field windings)
a 10 ohm resistor is connected across a 12 v battery. How much current is there through the resistor?
The wave function of a certain standing wave on a string fixed at both ends is y(x,t) = 0.30 sin(0.0025x)cos(300t) where y and x are in centimetres and t is in seconds. If the string is vibrating in its fifth harmonic, how long is it
