Question :
A 30kw, 300v d.c. shunt generator has armature and field resistances of 0.05 ohm and 100 ohm respectively.
Calculate the total power developed by the armature when it delevers full load output.
The signal m(t)=6sin(2*pi*t) volts is transmitted using 4-bit binary PCM system. The quantizer is of the midriser type, with a step size of 1v
Calculate the surface charge density induced on the plate as a function of the radius r from the foot of the perpendicular drawn from the charge.
Find the voltage across the circuit at resonance when a current of 1 µA is flowing into the circuit.
In RCL circuit connect with A.C. voltage, Inductor and capacitor increase thier voltage. For example Circuit connect with 230 V A.C. Voltage and frequency 4.96Hz. Inductor and capacitor's Vrms value become 1400V.
The radial field is provided by the coils in the stator to obtain a flux density of .2 Wb/m^2 so that there is one south and on the opposite side, the north pole. The coils on the rotor, 10 turns per coil, are connected in series through the commu..
The heavy duty battery can provide 9A for 4 hours period of operation each night. Design a parallel set of lights (select the maximum number of lights) when the resistance of each bulb is 12
The synchronous reactance of the generator is j1.35 per unit. Neglect armature resistance, armature resistance equals zero ohms. Both perunit impedances were calculated on the base MVA rating of thegenerator which is 75 MVA.
Construction on Hoover Dam was started in 1931 and finished in 1935, and the dam was in service from 1936. When completed, it was both the world's largest electric power producing facility and the world's largest concrete structure.
Point charges of 5nC and -2nC are located at (2,0,4) and (-3,0,5), respectively. A. Determine the electric field at all points in space. B. Determine the force on a 1nC point charge located at (1,-3,7).
A charge q is placed between two grounded infinite parallel conducting planes which are a distance "d" apart (see figure attached). Let ε_r = 1.
Determine the transfer function for a first order low pass filter with a cutoff frequency of 1000 radians per second and passband gain of 1 using Chebyshev type with 1-dB ripples on the passband.
