Consider a circuit that is connected to a phasor of 120V/0 degrees. The circuit feeds a 10 ohm resistor on the "hot" lead and then the circuit branches. One branch has a 0.1 A /-300 degree phasor current source (oriented with "arrow oriented right) and a series capacitor with reactance of 8 ohms. The other branch is an inductor with reactance of 8 ohms.If an external load is to be placed across teh current phasor source, find the Thevenin source equivalent of the circuit described. Draw the original circuit and the Thevenin equivalent circuit. What must the load be to extract maximum power from the circuit?
mutual shifted by 90 degree currents through each of both windings of the single phase A motor are (5.5+1.7) A but RMS voltage of the supply is 220 V. How big will be torque on shaft of the motor is efficiency factor (\eta\) is 0.7
design a multirange ammeter with ranges of 1-10mA,0-100mA, and 0-1500mA, using a 5mA movement whose internal resistance is 3.8ohms. draw a circuit diagram of the meter.
Along the way to the page, they pass into a region between two deflecting plates that are 1.6 cm long. There is a 1,500,000 N/C electric field between the deflecting plates. You measure the distance from the edge of the plates to the paper and fin..
Interface TTL logic to 120 VAC lamp. In this part of the lab, you will interface lowpower solid state electronics to the "outside world" by switching the 120 VAC lamp on and off using the AND gate from the previous experiment.
A three phase Y-connected 220-Volt 10-Hp, 60Hz, 6-pole induction motor has the following constants in Ohms per phase referred to the stator. R1=0.294, R2=0.144, X1=0.503, X2=0.209, Xm=13.25.
Determine the output voltage for an op-amp comparator circuit with a non-inverting input reference voltage of + 2 VDC and an inverting input signal of - 1 VDC. The op amp reaches output saturation voltages of ±13 V at the limits.
Consider a (Nt,Nr) =(4,4) MIMO channel. For the input of the channel x = [x1,x2,x3,x4] assume that each xi is drawn from a BPSK constellation with energy P. Also assume that the channel noise variance is σ2 =1
One of the biggest challenges with log systems, like the ones used for Intrusion Detection Systems data, is the amount of disk space that they require. For example, storing a message like: "User1 login success", contains 19 characters
A solar cell with an area of 4 cm^2 has I-V characteristics under illumination from a 600 W source it drives a load of 5 ohms. calculate power delivered to load and efficiency of solar cell.
A point charge of 16 nc is located at Q(2,3,5) in free space and a uniform line charge of 5nC/m is at the intersection of the planes x = 2 and y=4. If the potential at the origin is 100V, find V at (4,1,3).
