A 2000 kVA, 4800-600V, 60 Hz, core type transformer operating at no load in the step down mode draws a magnetizing current equal to 2 percent rated current. The core has a mean length of 3.15meters, and operated at a flux density of 1.55 T. The magnetic field intensity is 360 A-t/m. Determine (a)the magnetizing current (b)the number of turns in the two coils; (c)the core flux; (d)the cross sectional area of the core.
A quantum well has a finite-height barrier on one side and an infinitely high barrier on the other. Find the energies for the two lowest states for an electron in the well. The width of the well is L = 1 nm and the height of the finite step is Uo ..
A 120/240V single phase transformer is connected as an autotransformer. Suppose that V1 is 120V at zero degrees and the transformer is ideal. Find V2, I1, and I2.
an unknown three terminal device has leads named b,c and e. When installed in one particular circuit, measurements indicated that Vec=-9V and Veb=-0.65V. a) Calculate Vcb. b) Dtermine the power dissipated in the b-e junction if the current Ib
Find the total current I and the voltage across the capacitance. R = 420 ohms. capacitance = 292 ohms. inductance = 250 ohms. Source voltage 100 angle 0 degrees, 60 Hz.
Sketch the Capacitance-Voltage characteristics for both devices based on part (d) by giving appropriate labeling to the voltage and capacitance axis. You may assume high f measurements.
Build a circuit with the voltage input = 4 AA Batteries = 6V and the output = 3A Constant. The 3 amps output will be able to keep the TEC (Thermoelectric Cooler) on constantly. Try not to use any resistors/voltage regulators.
Draw a state transition diagram for a state machine that reads in a sequence of binary digits, one at a time, and stops when it has read in five 1s (need not be consecutive). To "stop" the machine, merely have it orbit in the state
Operation of NPN Bipolar Transistor : a. Describe the operation of a typical NPN bipolar junction transistor used both as an amplifier and a switch. b. List the 4 regions of operation and draw I-V characteristic curve.
A pn junction diode has Vd= 690 mv, C=6pF, Id= 500 microamps, Vt=.0259 V. It also has C=4pF when Id= 100 microamps. Derive the complete high-frequency model when Vd=610mV.
The transmit antenna gain is 2.1dB, and the receive antenna gain is 1.6dB. The received is 18Km away from the transmitter. The receiver has a Noise Figure of 8dB, Bandwidth 1.7 MHz and the Data Rate is 640K bps. You may assume T0 = 290K.
An 8mm thick brass [E=83 GPa; v = 0.33] plate is subjected to biaxial stress with sigma x = 180 MPa and sigma y = 65 MPa. The plate dimensions are b = 350 mm and h = 175 mm.
A true centrifugal casting operation is to be performed in a horizontal configuration to make cast iron pipe sections. The sections will have a length = 42.0 in, outside diameter = 8.0 in, and a wall thickness = .50 in
