Estimate how much magnetic field an electromagnet can produce at its gap, Hg. Assume that the pole-piece is horseshoe-shaped, with a total length of 1m, and the gap is 10 cm long. The pole-piece is wrapped by 500 turns of wire which carry i =1A The pole-piece has ur=1000 and Bs=0.5T. You can assume that Bg is equal to Bc and that under these conditions the core does not saturate.what is the value Hg (in kA/m)?
If the voltage on the secondary side is 13.8 kV and the power supplied is 4000 kW at 0.8 PF lagging, find the voltage regulation of the transformer. Find its efficiency.
The shaft output of a three-phase, 60 Hz induction motor is 100 HP. The friction and windage losses are 900 W, the stator core loss is 4200 W, and the stator copper loss is 2700 W. If the slip is 3.75%, what is the effïciency of the motor
Audio amplifiers use transformer coupling between the final amplifier stage and a speaker to match impedances and in order to avoid having DC current of the final stage flow through the speaker coil. We wish to connect an 8 Ω speaker to an 8000 Ω ..
A.) We would like to use a series lumped element b to match this load. What is the length of the line where the normalized input impedance is z= 1-jb(d/\lambda). If the rfequency is 1GHz , find the value of the lumped element(C or L).
In a MOS cascode amplifier, the cascode transistor is required to raise the output resistance by a factor of 40. If the transistor is operated at Vov = 0.2 V, what must its Va be. If the process technology specifies V'a as 5 V/um, what channel len..
A 4 pole 50 kW dc machine has a value of Ea = 110 V at 1100 rpm. What is the induced voltage is the speed is increased 20%. Note: omega(w) = (2f*n)/60 where omega is in rad/sec, and n is in rpm
What is the current i flowing into or out of the machine? What is the power flowing into or out of the machine? If the speed of the rotor were changed to 550 rad/s, what would happen to the current flow into or out of the machine?
A voltage source V = 119
Work out the following problem: If the analog signal to be quantized is a sinusoidal waveform, that is, x(t) = 6 sin (6283t), and if the bipolar quantizer uses 8 bits, determine 1. Number of quantization levels; 2. Step size of the quantizer ; 3. ..
A ¼ watt resistor has a resistance of 3.2KW what is the maximum current that the resistor can handle. If the wattage rating is doubled, will the maximum current double.
Let h(t)= (1/(R*C))*(e^(1/(R*C)))*u(t) be the impulse of an RC circuit and x(t)= u(t) an input to that circuit. 1. Find X(jω) and H(jω), which are the Fourier transforms of x(t) and h(t). 2. Form the product Y(jω)=H(jω)*X(jω) the Fourier transform of..
