A permanent magnet motor is driving a load that requires 0.08Nm.The motor data is:RA =2W, VA =12v,Kt =0:05Nm/A ,KG = 0:004 V/RPM . Find themotors running speed and the power output.
Design a full-adder using only a minimum number of 2x4 decoders. The complements of variables are not available but logic levels 1 and 0 are available.
A 40 Ω Resistor, a 5mH inductor, and a 1.25μF capacitor are connected in series. The series-connected elements are energized by a sinusoidal voltage source whose voltage is 600 cos(8000t + 20°) V.
Input Xi and Yi of each Full Adder circuit in an arithmetic circuit has the digital logic specified by the following Boolean functions: Xi =Ai Yi = B*iS + BiCin* Where S is a selection variable, and Cin is the input carry, and Ai and Bi are the inp..
Three loads are connected in parrallel across a 250 Vrms line. Load 1 absorbs 16 kW and 18 kVAR. Load 2 absorbs 10 kVA with a power factor of 0.6 leading. Load 3 absorbs 8 kW with a power factor of 1.
Calculate the number of resistors and switches needed for a resistor ladder DAC for each case: a. 3 bit DACb. 7 bit DAC c. 25 bit DAC d. 42 bit DAC
a) Design an inverting amplifier with a closed-loop gain of -100V/V and an input resistance of 1 KΩ. b) If the op amp is known to have an open-loop gain of 1000V/V, what do you expect the close-looped gain of your circuit to be(assuming the resist..
An unusual capacitor has a capacitance that is a function of time given by C = 2 + cos(2000t) μF in which the arugument of the cosine functionis in radians. A constant voltage of 50V is applied to this capacitor.
Find the magnitude of the electric field at all points in space both inside and outside the slab, in terms of x, the distance measured from the central plane of the slab. What is the field for x = 1.00 cm What is the field for x = 8.00 cm
Assuming that a 12-bit ADC channel accept analog input ranges from 0 to 20 volts, determine the following a) number of quantization levels b) step size of the quantizer or resolution
design a system comprising a pulley actuated by a stepper motor to lift objects of maximum mass of 1kg. No gear box is required. A 48 VDC power source is available. Select a pulley (specify the diameter) and a stepper motor.
An NMOS device has parameters V_TN=0.8V, L=0.8µm, and k_n^'=120µA/V^2. When the transistors is biased in the saturation region with V_GS=1.4V, the drain current is I_D=0.6mA. A) What is the channel width W
Compare the maximum theoretical PCE for 980-nm and 1475-nm pumping in an EDFA for a 1545-nm signal. Contrast this with actual measured results of PCE = 50.0% and 75.6% for 980-nm and 1475-nm pumping, respectively.
