Calculate the speed and the current when the motor field winding is shunted bya divert or of equal resistance as that of the field winding.Neglect all motor losses and assume the magnetic circuit a sunstaturated.
Add an activehigh overflow indicator and the required detection circuitry. Thecircuit should have inputs a7 through a0, inputs b7 through b0, sumoutputs s7 through s0, and output overflow. For all inputs/outputsuse index 7 as the MSB and index 0 a..
Let the segment registers hold the values (all in hexadecimal): CS = 2000H, DS = 3000H, SS = 3700H and ES = 7700H. Assuming segments are not allowed to overlap, what is the maximum number of bytes that each segment can have
A 1(lambda) wavelength long line has parameter R=0.2 Ohm/m, G=0.002 mho/m, L=15 muH/m and C=2.31pF/m. The line is operated at a frequency f=2.5 GHz. It is terminated with a load impedance of 100 Ohms.
Draw this electric circuit and the circuit can be composed of resistors, inductors, capacitors and opamps only. Then verify your circuit for any arbitrary DC voltage used instead of Vin by PSPICE.
1. A 3 phase, wye connected synchronous generator rated at 10kVA, 230V has a synchronous reactance of 1.2 ohms per phase and an armature resistance of 0.5 ohms per phase. Calculate the percent voltage regulation at full load if the power fact..
