Consider the magnetic circuit shown in Figure. The core has a relative permeability of 1500.
a. Carefully estimate the flux density in the air gap.
b. Determine the inductance of the coil.
Draw the individual and combined impedance (X pu) diagrams to a base of 10 MVA for the units and system - What would be the effect on the fault level of replacing the unit - Determine the pu impedance and the reactance of the interbus reactor for th..
Find Rin, Avo, and Ro. Also, if a load resistance of 10k ohm is connected to the output, what overall voltage gain Gv is realized. Now, if a 0.2 V peak sine wave signal is required at the output, what must the peak amplitude of Vsig be.
Problem: Consider the waveform x(t) shown below. The above signal x(t) consists of a DC component plus a sinusoidal signal. (The terminology DC component means a component that is constant versus time.)
A waveform generator is connected to an op-amp which has been setup as a voltage follower. The voltage follower is then loaded with a 50 Ohm resistor. What output impedance setting should the waveform generator use
A 117 V(rms), 60Hz household circuit has two 75 Watt lights,PF=1, and a fan using 500VA at 0.78 PF (lagging). A) Draw the circuit, representing each load by its impedance. Include the switches for each load. B) Determine the total current required fo..
smoke detector was loaded with 0.2u Curie when purchased 20 years ago. The isotope is Am-241with a half-life of 426 years. How much remains today
find the magnetic field in the space between the wire and the sleeve; and also in the space outside the sleeve. (that is , find the mag field at a distance 'r' from the center of the wire when b c )
Design an IIR BAND STOP Butterworth filter with the following characteristic
A half-wave rectifier circuit with a 1-Kwload operates from a 12-v(rms) 60-Hz household a 5-to 1 transformer having a center-tappedsecondary winding. It use two silicon diodes that can be modeled tohave a 0.7-v drop for all currents.
Design a 4 input, 1 output combinational circuit. the input represents a 4-bit number, N = X3X2X1X0, which ranges from 0 to 15. The output, PN is 1 when N represents a Prime Number, otherwise PN is 0.
The electric field in a certain region of space is given by the vector field E(r ) = E(x, y, z) = (x ? z)xˆ + (z ? y) yˆ V/m Find any two points P( x1 , y 1, z 1) and Q( x2 , y2 , z2 ) such that the electric field at P is perpendicular to the elec..
