a. For the system of Figure, the resistance of each line cannot exceed 0.006 Ω, and the maximum current drawn by the load is 110 A. What gage wire should be used?
b. Repeat (a) for a maximum resistance of 0.003 Ω, d = 30 ft, and a maximum current of 110 A.
Determine the ROM size and contents to implement a function which converts a sign and magnitude number from -5 to +6 to two's complement format.
An amplifier has a gain Ad,dB = 40 dB. Its common-mode rejection ratio is CMRRdB= 120 dB. It is used to amplify an input which has a 200mV desired signal along with an undesired common-mode signal ("noise").
Consider the data bus and the address bus. Which is bidirectional and which is unidirectional? Explain why each has its particular directional character.
A 3-phase induction motor, the equivalent rotor stand still reactance is equal to the reactance, while each resistance is (1/3)rd of this value. A torque of 500 Nmis developed at a slip of 5%. Calculate the maximum torque and thestarting torque.
A dc series motor has a armature current of 10A at full load. The motor terminal voltage is 300V. The armature and field resistances are 2 ohm and 3 ohm respecitively. The motor speed at full load is 250 rpm. Calculate the starting torque of the m..
The program is to input the number character-by-character and then assemble them together so that the original number is put into a floating point variable and displayed back to the monitor.
special signals and spatial frequencies generate images of sinusoidal signals with spatial frequencies fx 5cph fy
It is operating in parallel with a 480-V 150-kW four-pole 50-Hz synchronous generator whose prime mover has a no-load speed of 1500 r/min and a full-load speed of 1485 r/min. The loads supplied by the two generators consist of 200 kW at 0.85 PF l..
(a) With respect to absorption of radiant energy, what distinguishes a greenhouse gas from a nongreenhouse gas? CH4 is a greenhouse gas, but N2 is not. How might the molecular structure of CH4 explain why it is a greenhouse gas?
Classify these fields according to the Helmholtz theorem.
Calculate power factor of the motor at no load. - Calculate phase difference of voltage and current in two wattmeters.
What happens to the propagation delay of the N-bit full adder as N is increases from 2 bits to 32 bits Compare and contrast this method of building an adder with the carry look ahead method described in your textbook
