An electric circuit is powered by unpolarized 120V, 60Hz outlet. The circuit is inside ungrounded chassis. A 100nf capacitance exists between the circuit and the chassis. If a man touches the chassis, compute the current through his body. Assume that the body resistance of the man plus his ground resistance is 1000Ω.
A three-phase, 5 hp, 208 V, 60 Hz induction motor runs at 1746 rpmwhen it delivers rated output power. (a) Determine the number of poles of the machine. (b) Determine the slip at full load. (c) Determine the frequency of the rotor current.
What Role Power factor play in AC circuits and power dissipation ? and What are the Disadvantages of Low Power Factor ??
A harmonic wave traveling along a string is generated by an oscillator that completes 180 vibrations per minute. If it isobserved that a given crest, or maximum, travels 300 cm in 10s,what is the wavelength
Why is power normally sent in bulk
Explain the major differences between a motor and a generator. Explainin detail how the simple motor worksand be sure to include the functions of the reed relay and transistor.
A first order lowpass filter is operating in sinusoidal steady state conditions at a frequency of 2 kHz. It is determined that the positive peak of the output is delayed by 0.1 ms compared with the positive peak of the input.
Assume the mass of the cup and water to be equal to the mass of water alone. Calculate the normal force FN for 300 g and 150 g.
An LTI system's impulse response is described by the differential equation, dh(t)/dt + 3h(t) = impulse function. Find the characteristic roots for the system, the initial condition, and the h(t) for t > 0.
Plot the VTC of a CMOS inverter and alculate the waveform - Your answer should look like this - Use FindRoot to calculate TPHL and TPLH for the first stage inverter and the second stage inverter.
An FM receiver has a Foster Seeley discriminator that has a transfer ratio K = 0.03v/khz. If the maximum IF deviation is 75Khz, what is the maximum output voltage of the discriminator What is the minimum output voltage of the discriminator
a) what is the order of this approximation b) Suppose |f(x) - g(x)| 0 is as large as possible what is μ
