1. Calculate the dc resistance in ohms per kilometer for an aluminum conductor with a 3 cm diameter.
2. Calculate the dc resistance in ohms per mile for a hard-drawn copper conductor with a 1 inch diameter. (Note that 1 mile = 1.609 km).
3. Calculate the inductive reactance of this line in ohms.
4. Assume that the 50 Hz ac resistance of the line is 5% greater than its dc resistance, and calculate the series impedance of the line in ohms per km.
Steel rods AB and BC each have a diameter of 5 mm. If the load of p= 2 kN is applied to the ring, and if ? = 60°, determine the following:
The power transferred across the air gap of a two-pole induction motor is 24kW. If the electromagnetic power developed is 22kW, find the slip. Calculate the output torque, if the rotational loss at this slip is 400W
A aperiodic signal x(t) = 2sinc(2t) is multiplied by a periodic rectangular pulse train s(t) with fundamental frequency F0 = 4 Hz and the fundamental rectangular pulse given by p(t) = 1, -1/80
A six pole, 40 kW, 400 V d.c. motor draws 110 A from the supply. The shunt field resistance is 200 Ohm and the armature resistance is 0.5 Ohm. The armature is wave wound with 600 conductors operates at a speed of 1200 rev/min when supplying full l..
Develop a register file that has 8 5-bit registers. The user can read or write to any of the 8 locations. Develop a state machine that causes the ALU to perform the operations and store the results to the registers.provide de VHDL code ths\is
Sketch the magnitude characteristic of the transfer function H(jw)using a Bode Plot. Label all critical values and identify the typeof filter the circuit represents. use C= 1000u F, L = 10H, AND R =100 ohms
1. Calculate the frequency for each of the following periods:
A system with many components has 3 sensors (x, y, and z)monitoring separate sections of the system. Given that sensor xgenerates an output if there is a mild fault, sensor y generates anoutput if there is a serious fault
The DC shunt motor is running at full load with a supply voltage of 440 V and a supply current of 70 A. The rotation speed in full load is 1000 rpm, the field resistance is 200 Ohm and the armature resistance is 0.2 Ohm.
Design a Mealy sequential machine with two inputs A and B, and one output Z. Output Z generates 1 if: (a) A had the same value at each of the two previous clock ticks, or (b) B has been 1 since the last time that the first condition was true.
