1. Because the circuit below stores energy in the capacitor and in the magnetic field of the inductor and the gnergy is simply transferred back and forth on alternate half-cycles, this circuit is commonly called a
2. Using the circuit below, create a graph of Xr, Xc and Z'vs. frequency. The graph should include frequencies r'rom 500Hz to l0kHz in 500Hz in cremen 'ts.Your graph should look similar to Figure lT-16 in your textbook. This must loe done digitally with EXCEL or equivalent graphing software. Locate and laloel the resonant frequency on your graph. Looking at your graph, approximate the value of the resonant frequency/, =
3. Calculate the resonant frequency using Equation L7-4 from Ch. 17 in your text Fr=
4. If ihe winding resistance of the coil is I OO f) , calculate the precise resonant frequency(Equation 17-13).fr,=
5. Determine the lower critical frequeircy and label this poirrt otl your graph. fα =
6. Determine the upper critical frequency and label this point on your graph. fcu =
A composite load consists of 3 loads connected in parallel.Onedraws 100W at a power factor of .92 lagging, another takes 250W ata PF of .8 lagging, and the third requires 150W at a unity PF.The parallel load is supplied by a source Vs in series wi..
A one-dimensional infinite potential well with a width of 12 Ao contains an electron. (a) Calculate the first two energy levels that the electron may occupy. (b) If an electron drops from the second energy level to the first, what is the wavelengt..
how do you determine the value of Xl in a parallel resonant circuit, when all youre given is Xc, Rcoil, and the parallel resistance
A transmission line has a resistance of 0.001 pu , and 0.01 p.u reactance. Voltages at the both ends (p and q) of the transmission line are 1.0p.u each. Angle at bus "p" is 45o and the angle at bus " q" is 30o.
A 10m diameter cylindrical tank is emptied by a constant outflow of 1 m3 /min. A two position controller is used to open and close a fill valve with an open flow of 3 m3 /min. For level control the neutral zone is 1m and the setpoint is 10m.
An inverter has a measured delay of 2ns. If five identicalinverters are connected in series, where the the first one isconnected to the last inverter, such that the voltage at the firstinverter will be an oscillate like a clock.
1. Derive boundary conditions for electric fields (both for tangential and normal components) 2. Derive boundary conditions for magnetic fields (both for tangential and normal components) 3. Why boundary conditions are so important in electromagnetic..
Suppose that the number of customers entering a department store in a day is a random variable with mean of 50 customers/day. Suppose that the amounts of money spent by each one of these customers are statistically independent.
1. What would you need to understand about a CPU's architecture to take pseudo-code and convert it into programming instructions 2. What files are generated by CodeWarrior when you assemble an assembly language program with no errors
Let a 4x inverter have transistors four times as wide as those of aunit inverter. If a unit inverter has three units of inputcapacitance and parasidic delay of pinv, what is the input capacitance of a 4x inverter
Design an alarm circuit to be used in a process control system. Temperature (T), pressure (P), flow (F), and level (L) of a fluid are each monitored by separate sensor circuits that produce a high logic output signal when the following indicated p..
