A P=900W electric motor with pf=0.82 lagging is connected to a 240 Vrms 60 hertz source.
a) Draw an equivalent circuit showing impedance and phasor values for Vs, R and X.
b) Find an Xc value to put in parallel with the motor which corrects the pf to 1.0.
c) Find the source current (Is) before and after (Is*) the Xc is added.
Design a DC current source to meet the following specifications: - Current source value: 100 u-amps +/- 1% (over all possible load and supply voltage conditions). - Output resistance: >20 Mohms. - Available DC voltage sources are bipolar and range fr..
A waveform generator has been setup with a square wave output at 4.0kHz with a 81% duty cycle. If the peak-to-peak output amplitude has been set to 6.0V, with an offset of -1.0V, what is the maximum voltage of the output waveform
Important information about Digital signal processing, (a) Design a lowpass FIR digital filter using "remez" routime in Matlab for the following specifications:
A double-A (AA) rechargeable battery is rated at 1.2V, 2100mA-h ( mili-amp hours) 1- how many coulombs of charge can this battery hold 2- how many joules of energy are stored in the battery
Use Laplace transform techniques to find the solution to the following differential equation given that x = 1/3 at t = 0.
Basics problems of Induction motor, The frequency of the induced rotor currents in the rotor of a 60 Hz induction, machine is 2 Hz. Furthermore, the fields in the air gap turn at -40 rpm with respect to the rotor.
What is the PIV required of the diode? A half-wave rectifier employing a 12-V-rms 60-Hz sine-wave source and no dc load is filtered using a polarized electrolytic capacitor having a small leakage current.
First you must give all different possible connection types for them and then, for each case, you should develop some tests that can define the connection type and calculate the current passing through the capacitors.
Finding peak amplitude, frequency, and spectrum shape, b. A signal generator outputs a unipolar square wave with a period of 0.50 ms and an amplitude of 2.0 V. The output of the generator is passed through an ideal band pass filter that has a pass..
Important information about RC Series Circuit, An RC series circuit has a voltage source of 10Vac, a resistor of 10ohms, and a capacitor with an impedance of -j10ohms
Write a MATLAB program to compute the capacity of an AWGNC with a given bandwidth and for equally spaced values of between and including and (in dB).
Saw on internet some equations to convert from frequency in hertz to mph. Some equations need a gear ratio while others do not. I found the equation mph = circumference * RPM * 60.
