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.
mesh analysis involves writing and solving a number of simultaneous equations. The number of equations is equal to the number of independent loops in the circuit. Each equation is derived from the application of KVL around the loop.
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
Given a voltage of 100 volts with a phase angle of 0 degrees, applied across an impedance of 50 ohms at an angle of +30 degrees. This is an inductive impedance - not TOTALLY inductive, but more inductive than capacitive.
A. determine the mean, variance, and standard deviation B. find the three quartiles and the interquartile range C. Prepare a box plot for the data and determine if there are any outliers present.
A saturated npn transistor has a base to emitter applied voltage of 0.6V. The collector to emitter voltage is 0.2V. The collector current is 12mA
Determine the cost per kilowatt hour for the energy delivered by a typical alkaline 9-V "transistor" battery that costs $1.95 and is capable of delivering a current of 50 mA for a period of 10 hours. (For comparison, the approximate cost of energy..
1.write down the electrical status equation for the circuit with serial connection of RLC- elements in vector form and darw diagram for this circuit. 2. Describe the work of electrical source in the voltage generator regime. and what is the working..
With the multi function gate: F = X'AB + YA'B + X'AB + YAB' 1. Can this gate be used as an inverter If yes, how 2. Will the change in the number of inputs or outputs affect the number of operation select lines Explain.
A signal is bandlimited to 20kHz. The band between 16 and 20 kHz is corrupted by noise such that the information is unrecoverable. Determine the analog lowpass filter maximum frequency to eliminate corrupted noise.
Discuss the differences between series and parallel circuits. What are some advantages and disadvantages of each type Discuss why the total power equals the sum of the individual values of power, whether a series circuit or a parallel circuit is u..
A wattmeter connected into the line gives a reading of 2765W. If a capacitor have a reactance of 30ohms is connected in parallel with the motor. Calculate the total reactive power absorbed by the capacitor and motor.
A majority function is generated in a combinational circuit when the output is equal to 1 if the input variables have more 1's than 0's. The output is 0 otherwise. Design a 3-input (A, B, C) majority function. Use K-maps to simplify the circuit. D..
