A certain appliance has a potential difference of 100volts while getting a current of 1.5 amperes. Calculate the rate atwhich energy is changing in this appliance.
The noise voltage in an electric circuit can be modeled as a Gaussian random variable with 0 mean and 10^-4 standard deviation. This noise passes through a half wave rectifier with the characteristics g(x) = { x, x>0 and 0, x
The bandwidth of interest is between 0.5 and 50 Hz and has peak amplitude of approximately +/-1 mV. -a. Design and draw a block diagram (not circuit) of the signal conditioning portions (everything before ADC) of your system.
The z-transform X(z) of a causal sequence x[n] has a zero at z1 = 0 and three poles at p1 = 3/4 and p2,3 = (1/2)(1 ± j). Determine the z-transform Y(z) of the sequence y[n] = x[n + 3], its pole-zero pattern, and its ROC.
The simple inexpensive hydro turbo-generator (turbine mated with electric generator) that you intend to buy has a working efficiency of 60%. Answer the following (show your work).
A particular load has a pf of 0.8 lagging. The power deliveredto the load is 40 kW from a 270-V rms 60-Hz line. What value ofcapacitance placed in parallel with the load will raise the pf to0.9 lagging
Then find the total energy stored in the battery before it is connected to the bulb. Determine the total amount of charge that has pessed through the wires that connect the battery and the bulb.
Then, solve each Problem using hand calculations. A three-phase, 765-kV, 60-Hz transposed line is composed of four ACSR 1,431,000, 45/7 Bobolink conductors per phase with flat horizontal spacing of 14 m. The conductors have a diameter of 3.625 cm ..
You happen to have a 5-V regulated power supply that you bought at Midwest Surplus Electronics in Fairborn, Ohio. Measuring the output voltage with your trusty voltmeter, you get an open-load reading of pretty close to 5 V.
A conducting rod of length L rotates at constant angular speed w about one end, in a plane perpendicular to uniform magnetic field B. (a.) Show that the potential difference between the ends of the rod is 1/2l^2Theta.
At a temperature of 770 C find the resistivity of ptype Si with Na= 1015/cm3. For the doped Si at the given temperature assume μn=1000cm2/V.s and μp = 350cm2/V.s.
Estimate the size and weight of an 1970 automobile using 1970 electronics technology which would have the equivalent computational power and electronics a typical 2013 automobile.
The transfer function of a system is given below. Find its impulse response in n-domain. Hint: First expand using partial fraction expansion and then perform its inversion using z-transform tables H(z) = 1/(z-0.5)(z0.5)
