The eddy current loss in a particular magnetic circuit is 10 W/m3. If the frequency of operation is reduced from 50 Hz to 30 Hz with the flux density remaining unchanged, determine the new value of eddy current loss per cubic metre
any noise will pass straight through to the ADC subsystem, introducing measurement error. You have two choices to mitigate this: SW filtering and HW filtering. Either way around, you need a HW anti-aliasing (low pass) filter following the output.
The NMOS transistors in the circuit shown in Figure P16.68 have parameters Kn =0.2mA/V2,VTN =0.5V,λ=0,andγ =0.(a)Forgatevoltagesof φ = 2.5 V, determine the quasi-steady-state output voltage for (i) vI = 0
A six pole,60 Hz synchronous motor is connected to an infinit bus of 15 KV through a transmission line.The synchronous reactance of the motor is 5 ohm ,and the inductive reactive reactance of the transmission line is 2 ohm
Design a linear broadside array to have nulls along the directions θ = 50°,130°, and 0° , namely find the number of elements , and the relative currents , find the beamwidth to nulls and the side lobe level .
HCI is a polar molecule, with a dipole moment of 3.44 X 10^-30 [C.m] per molecule. If it is known that the molecular bond distance is 0.136[nm], find the magnitude of the net displaced charge in each molecule.
A certain engine lathe can be purchased for $330,000 and depreciated over three years to a zero salvage value with the SL method. This machine will produce metal parts that will generate revenues of $220,000 (time zero dollars) per year.
Two stages are cascaded to result in an overall gain of 680 V/V.The loaded gain of the first stage is 36 dB. What must the gain ofthe second stage be in dB to satisfy this specification In V/V
A shunt DC generator has a termianl voltage duringopen-circuit of 127V. When the machine is operating at rated load,the rated terminal voltage is 120V. Find the load current ifthe field resistance is 15 ohms and the armature resistance is 0.02ohms..
The torque produced by an external magnetic field is torque = D[5i,-3j] where D is a positive constant, and for this orientation of the loop the magnetic potential energy U = -mu cross B is negative. The magnitude of the magnetic field is 14D/IA
