Consider a permanent magnet dc motor with the following parameters; Ra = 0.35 ohms, La = 1.5 mH, Ke= 0.5(V/(rad/s)), Kt= 0.5 Nm/A and Jm = 0.02kgm^2. The rated torque of this motor is 4Nm. If the motor is driving a load whose torque requirement remains constant at 3Nm, independent of speed. Calculate the armature voltage Va to be applied in steady state, if the load to be driven at 1500RPM.
Electrical wiring: Potentials of neutral and earth wires, Why is the neutral wire in housing circuits also at zero potential
Write and test a C program that outputs a waveform that switches from 10.0 kHz with a 50% duty cycle to 25.0 kHz with a 5% duty cycle every 5 seconds. Your code design must be modular - initializations and program operations are to be performed
A 10 kW, 220 V, dc shunt motor has field and armature reistance of 110 ohms and .20 ohms, respectively. At no-load the motor runs at 1200 rpm and has an armature current of 5 A.
design an arithmetic incrementer/decrementer circuit. Your circuit will recieve a 3-bit binary number (A) as input to produce an output which is either A+1 or A-1 depending upon the command input (ID).
What are the respective advantages and disadvantages of the asynchronous and synchronous communication modes from a reliability perspective?
Find the density for germanium (Ge) semiconductor atoms give that its lattice constant a-5.66Å (Angstrom) and atomic weight is 72.59 g/mole.
The average orbital radius of Neptune is 2.8 billion miles. Given that distance, how long on average does it take light from the sun to reach the planet Neptune in hours (Speed of light in English system = 186,282.4 miles/second)
Explain in detail on the fabrication process of the FINFET. You must show a 3-dimensional view of FINFET and label the its L and W, the length and width of the gate.
A hydroelectric power plant has a synchronous generator who's speed must be fixed at 180 r/min. The turbine is Pelton type with 10 m runner diameter. When the flow rate at the nozzle of the penstock is 10m^3/s, the generated electricity.
The internet connection speed at any time from your home can depend on the amount of overall internet trac at that time. Let the random variable X denote the speed of connection in megabits per second (MBPS).
Design an amplifier circuit to amplify the small output voltage of a transducer of 50mV peak to deliver an output voltage of 8V peak to a 10k ohm load. (This design will produce 1 simulated circuit and an ac output and gain verified using an oscil..
A signal x[n] is formed by sampling a signal x(t) = -4sin(200*pi*t) at a sampling rate of 400Hz. Graph x[n] over 10 fundamental periods versus discrete time. Then do the same for the sampling frequencies of 60 and 200Hz.
