An AC voltage of 240 volts with frequency of 60 Hz is applied to 0.5-H inductor. Assuming that the inductor was pure of ideal (no resistance; inductive reactance only), how much current would flow through it?
Find the max instantaneous power delivered by the source, dissipated by R, and absorbed by L. What are the smallest instants (t > 0) at which these maxima occur.
Consider an industrial load that absorbs 40 kW of power with power factor 0.8 lagging from a 60-Hz transmission line of voltage VL= 240
The frequency is t = 300MHz. The medium is vacuum. Find the wave vector k and write the expression for the vector field phasor E at the point [0,sqrt (2)] bearing in mind that the field phasor at the origin is E(0,0,0) V/m.
Use the simulation timing diagram to compare the worse case time to do an operation with your ALU with the worst case using the 74LS381. State which operation takes the longest and list the time required for both ALU's.
The x-y plane separates dielectric material with εr1=2.0 (for z
Find an interesting (yet simple) circuit (LED flasher, battery charger, audio vu meter, etc.) on the internet and explain (as best as possible) how the circuit works. How does it utilize diodes, resistors, capacitors, transformers.
A PWM is to be programmed to output a signal with a pulse high width of 150 usec and a pulse low width of 250 usec. What are the values required for prescale (if any) PWMPER and PWMDTY An 8-bit configuration is used and the E-clock is 24 MHz.
A large brass washer has a 2-cm inside diameter, a 5-cm outside diameter, and is 0.5 cm thick. Its conductivity is s = 1.5 × 107 S/m. The washer is cut in half along a diameter, and a voltage is applied between the two rectangular faces of one par..
A series-resonant RLC circuit has R = 80 (ohms), L=25mh, and C=10pF. A) Sketch and label the circuit. B) Find fo, the resonant frequency. C) At what frequency is impedance a minimum D) What is the magnitude of the impedance at this frequency
A six pole, 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 load.
a) Plot the spectrum and the normalized spectrum of x[nT] = 2cos(20*pi*n*T + pi/8) + 4cos(40*pi*n*T + pi/8) for T = 0.01 b) Plot the spectrum and the normalized spectrum of
It starts from rest at the origin. Show that it moves in a cycloidal path and drift velocity or the velocity of the center of the rolling circle along the z axis. If the electric field is 10^4 volts/cm, and the magnetic field 10^4 gausses. find th..
