A permanent magnet commutator motor produces a torque of8 N. m with armature current = 10A. armature R=.16 ohms. if motordrives a load requiring torque of 20 N. m at speed = 1800rpm, what must the voltage applied at the armature terminal be?
A majority function is generated in a combinational circuit when the output is equal to 1 if the input variables have more 1's than 0's. The output is 0 otherwise. Design a 3-input (A, B, C) majority function. Use K-maps to simplify the circuit. D..
Design the simplest circuit that has three inputs, X1,X2, and X3, which produces an output value of 1 whenever exactly one or two of the input variables have the value 1; otherwise, the output has to be 0.
Design a digital circuit that can be attached to a school bill which can work automatically from 7:00 AM to 12:45 PM, and it has the following features: 1- Rings for 5 seconds. 2- Start ringing 7:00 AM to announce for the field gathering. 3- Rings 7:..
The nameplate on a 50-MVA, 60-Hz single-phase transformer indicates that it has a voltage rating of 8.0-kV: 78-kV. An open-circuit test is conducted from the low-voltage side, and the corresponding instrument readings are 8.0kV, 62.1A, and 206kW.
An FM signal being transmitted is represented by eFM(t) = 50Sin((2)(95.1)(106)t+2Sin((2)(10)(103)t)). If the antenna impedance is 75 , determine: (a) total power in FM signal and (b) FM modulation index.
a) Find the two values of vGS that give there spective limiting values of resistance b) Estimate the maximum permissible amplitude ofvDS for this resistor to operate as a linear device
Now assume that the doctor knows that 1 in 100 individuals with symptom G will have the rare disease, and he only orders the test when individuals have symptom G. Given that one of the doctor's patients tests positive.
Design a sequential circuit which adds two to a binary number in the range 0000 - 1001. The input and output should be serial with the least significant bit first. Find a state table with a minimum number of states.
A conducting filament containing a small 400 ohm resistor is formed into a square loop on the x-y plane as explained in the previous problem. Find I at t = 2*10^-4 sec if (a) \(B = 3cos(12000\pi t)a_z T\)
If a zener diode has a breakdown voltage of 8[V], find the dielectric strength of the semiconducting material if it is assumed that the entire voltage is dropped across the pn junction,which has width 0.3[μm]. Assume that E is uniform across the j..
A constant torque of 5Nm is applied to an unloaded motor at rest attime t = 0. The motor reaches a speed of 1800rpm in 4s. Assumingthe damping to be negligible, calculate the motor inertia.
